THE MITOCHONDRIA IS THE POWERHOUSE OF THE CELL
Where is this sentence/ comparison actually "originally" from? What is its earliest source ?
THE MITOCHONDRIA IS THE POWERHOUSE OF THE CELL
Peter Nitzer the first ever biology teacher
Aha... Philip Siekevitz 1957 ( supposedly)
"every species except one"
The prevalence of that phrase will drive a taxonomist insane!
Why?
soooooo many biologists have claimed the species they found to have x trait is the only one to have it, just to be shown not to be the case years later
@@MGgoose1 well wen you have little evidence that it could even happen one really dosnt bother.
Because, all mammalians have life birth, expect two. Too much metal in the soil will kill plants, except one tree. The female of the species carries the offspring, except on seahorses. And many more examples.
@Meek Peace still. You'd think an educational show would be more percise.
Human 1: This species is unique, among all life in such a fascinating way!
Human 2: Great! We can use that knowledge to kill it, it's eating my fish!

Humans can't even defeat the covid-19 so how are they suppose to kill something that doesn't even breath?
@@huldu you have knowledge that corona can breathe?
@@huldu one has nothing to do with the other, and there was a time humans did not know how to defeat anything, and survive by luck.

Right! Sounds pretty fishy to me...

I thought whales and dolphins have flukes, not fish?
Mitochondrial are wierd. To think that something one of our ancestors ate kept on living inside it 🤔🤔
Life, uh, finds a way.

Multiple bacterial parasites do this with insects, passing themselves down through egg cells. So it's not uncommon.
@@garethdean6382 what is this processes called when they do this?
@@garethdean6382 yeah but it's kinda unique cuz mitochondria have their own DNA, as opposed to when a parasite simply becomes a part of the host's DNA...

Well now we know that exoplanets don't need oxygen to host complex life.
There's still a question of how big it can grow and how intelligent it can get since anaerobic metabolism produces less energy.
@@Fif0l or they could use some completely different method of anaerobic or aerobic energy production that is sufficiently energy-efficient to support complex life. Perhaps one based on their own atmospheric composition or random genetic history.
Water has lots of very wonderful and unique properties that make it so good, even necessary, for life, but the universe is filled with reactive gases ready to steal electrons.
@Pepito And you know this because you went to these planets and sampled thousands of places and none of them contained any life?
@Pepito Right, because *researchers* went to these planets, sampled everything, and found nothing. Not you personally. That totally makes it different.
Man I really got to quit arguing with literal children on the internet. They're extremely stupid, extremely stubborn and extremely vain, all at the same time.
@Pepito What's ironic is that your "lmao faith" speech about my statement supported by scientific evidence, is driven by your own faith not only not supported by anything, but in fact which has evidence to the contrary.
Can confirm that Journey To The Microcosmos is a great TH-cam channel.
Probably my favorite channel of all. The only one I prepare myself to watch, as we usually do for TV shows.

Journey to the Microcosmos is unbelievable beautiful and off course you have to dig in your brain back to far far away when you learned about these tiny creatures in school. I’ve been following them from the beginning. They are certainly worth your time.
1 occasional vocabulary error: mitochondria is plural. The singular is mitochondrion

Great Job Olivia! Good Presentation 👍!
I love the MicroCosmos. I love the calmness.
journey to the microcosmos! hell yeah
Great video as always. And btw Olivia you are looking especially pretty in this vid!
I stumbled onto this video while researching this interesting little "Animal" "Species". It, as well as possibly the whole Myxosporea class, seems to have most likely evolved from Cancerous Jellyfish cells, so have a very unusual evolutionary path.
I heard a similar story about some Cancerous Dog Cells becoming free living single celled organisms, that were Genetically Dogs. I think that story came from Sci Show too...
Think about this for a second, if we strictly use genetic markers to determine where different living things are placed, then potentially, this single strange celled organism could be classed as a Vertebrate, specifically a canine. I'd love to see a taxonomist who purely classes based on genetics figure out where to put that thing on the tree of life! This is pretty much what is probably going on with this species in the video, Henneguya salminicola, except this organism is hypothesized to be from a Jellyfish, rather than known to be from a dog.
Thats mind-blowing

Your comment have translation, how????????
@@Usuario459 No offense, but have you ever seen The Lion King movie?
My understanding was before the ‘great dying’ most life wasn’t o2 dependant. Was it just plant and bacterial life back then?
Thank you!!! Now I know how do they make energy.
Great clip and great narrator!
Imagine Martian lifeforms that never evolved to use oxygen or a mitochondria to become space traveling aliens.
i learn more from this show than i ever have in school
Yeah for sure😂
Does this also confirm that extraterrestrial life may not rely on oxygen to survive?
An exception we never expect
This was stupidly fascinating! :D
Miss ya, girl! You were one of the best!
When did Olivia stop wearing glasses? Just wondering, as this is the first time I've seen her in a episode without glasses.
Ravioli Pillar I know, right?? Was literally scouring the comments to see if anyone noticed too. I love glasses! On everyone. O-O.
I'll take her either way. I love her as host!
Contacts my dude, try em.
This is the first episode I've seen her without glasses or makeup. I almost didn't recognize her at first. The only thing that sounded similar was her voice.
List of things humans need to survive:
-Food
-Water
-Air
-Sleep
-Shelter
-Wifi
Did you know that there are some multicellular creatures that have _no way to access wifi?!_
I have found a substitute for the last one, it turns out, stick with me now, it turns out that humans can survive for extended periods of time with just unlimited LTE only occasionally having to venture out to find wifi to do things like take quizes or do homework on their laptop while lookibg up answers on their phone, i theorise that with 2 phones they may be able to survive solly on LTE but i believe that may only be for the life stage "student"
Toilet paper
@@ConstantChaos1 a few select humans can also survive by connecting these long strands of metals, twisted together linking them to the world at large in lieu of wifi.
@@kalmtraveler i believe ive seen inwtances of that as well, my mother infact lost her ability to utilise wifi and found that method still worked
Thank you.
She was breathing through this entire video.
GENIUS!

Thanks for remembering that the word mitochondria is plural.
We don’t obtain energy from oxygen. It’s used as a terminal electron acceptor.

Yay I like science. I like learning.
great video
i dig your new look
Will this be on the final?
I totally said it with you yessss I feel accomplished today.

Since they are presumably missing most or all of the Mt electron transport chain, are they simply fermenting their sugar and if so, what are the products of that fermentation?
Scientist: We found this amazing one-of-a-kind organism!

"Natural selection can drive genetic change, but so can pure random chance." This sentence makes no sense...
1: Chance is always random.
2: Genetic changes (mutations) always occur randomly and if this increases the chance to pass on the genes to the next generation then this mutation becomes more common and can even become the only genotype. Natural selection does not "drive genetic change" it is a result of genetic change and it can cause mutations to become fixed within a population.
3: Mutations that are neither beneficial nor deleterious can become fixated if there is no selection pressure against or for it, this is indeed by chance, but even here natural selection plays a roll, because fitness is still a factor, it can't be affected to negatively...
And you just explained that it is a beneficial for an species to lose genetic information that it doesn't need, so it wasn't genetic drift that caused this, there was a clear fitness advantage to the mutations that lead to losing it's mitochondria.
she talked about natural selection, and natural selection does drive genetic change (sexual reproduction, predation, etc) and isn't random. and if she said its pure random then it was probably genetic drift, just because its random doesn't mean it can't be beneficial. a fish living in a cave with no light has no actual evolutionary pressure to lose its eyes, they lose it by genetic drift, but that doesn't mean that losing their eyes is not beneficial, now they don't have a huge vulnerability on their faces. the same way just because a animal adapted to live in low oxygen conditions, that doesn't mean there is a genetic pressure to lose the ability to process oxygen, but since its is not using those genes, it will eventually lose it to genetic drift. that doesn't mean it had to be genetic drift, it could very well be natural selection, and the way she said it doesn't make it very clear, but I'll just assume she was referring to genetic drift because she said it was random.
@@danilooliveira6580
absolutely right. she was differentiating between selection and drift without using jargon... because your typical youtube watcher is, well, mostly uneducated and bored by jargon.
I knew it would be Olivia
When we see a contradiction contradict a contradiction we assume it has no purpose we need to assume that we are making assumptions.
Dear Sci-show! I am glad to have stumbled on this channel several years ago! You have inspired me to start my own channel and my second video of "Why There May Be a VR Exodus"!
Nice!
Sounds very cool!!
The 👏 Mitochondria 👏 is 👏 the 👏 powerhouse 👏 of 👏 the 👏 cell.
You know everyone is lowkey thinking 'Yeah'
Very interesting.
The people I sat next too in lab discovered this :) awesome science!
why did they work on this particular parasite?
@@pramitbanerjee Myxozoa is one of the main creatures we worked on. I think it is because even before they became the only animal that doesn't breath, They were already so WEIRD. I think they are also the only Animalia that spends most of its time as a single celled creature.
I also worked on Myxozoa, but something else completely, I did Myxozoa-Cnidaria phylogeny.
Mitrocondria is the powerhouse of cell is such a universal language. Everyone understands and pleased to say it. haha!
Came here for the "mitochondria is the powerhouse of the cell," stayed for the "PNAS"
Olivia, you have a lovely voice.
COULD IT SURVIVE ON MARS
Animal - I instantly thought mammal
My hopes were dashed in seconds
So... this is the episode of SciShow that makes breathing manual?
Are we sure that it's mitochondria related organelles didn't just branch off from mitochondria before either branch started producing energy from oxygen instead of losing the genes to do so after the fact? Like is all the other DNA close enough to other myxozoans that it had to have branched off later?
Throwback to high school
Virus parasite thingy : you cant kill me! I dont even need oxygen!
Humans: .....hmmm..... feed it oxygen.
Virus thingy: wait what
What about the anaerobic Loriciferans that you covered a year before this video?
Well this is really interesting!
Also, given 4 weeks ‘chest infection’ I didn’t think I would ever be jealous of a parasite...
If only we could all be more like Henneguya salminicola,
what a wonderful world it would be...
"Pfft, oxygen? What's that?"
I mean i survive without sleep so maybe lmao
As a biologist, I really think that the evolution of mitochondria is amazing! We think that the last common ancestor of eukaryotic cells took up a prokaryotic cell which survived and gradually became what we now call mitochondrion. Over the course of millions of years mitochondria lost more and more of its own DNA which was integrated into the host's genome. Today many building blocks of mitochondria is actually found in DNA inside the nucleus (although I'm more doing biomedical research on my channel, I would love to also cover more evolutionary biology)! Amazing, right?
The fact that many Wolbachia species have integrated themselves into insect hosts always makes me wonder if out there there's not another version of mitochondria hanging about.
It's kind of like mistletoe which has lost it's mitochondria in some species
She saying oxygen so many times, I now have to go play Subnautica ... congratulations
Yes, mitochondria ARE powerhouseS of cells
I imagine this discovery will also expand the types of places we'll be searching for life in outer space.
Inside Salmon right?
Not really, we already know of plenty of life that doesn't need oxygen which is why we're looking at Europa and Titan as possible places of interest. It doesn't even really change much where we'd look for animal life, we know of species that live free from oxygen but use other chemicals in the same role.
Stay safe, Olivia.
But like, what chemicals does it use for energy? I mean, sugars, but aside from those how does it metabolize them and how exactly does it's mitochondria-like-organelle work?
I was honestly expecting to hear more about how it survives without oxygen and less about its environment. Still a good video though.
I have nothing relevant to the video to say so I shall tell a science joke instead.
Oxygen has started dating Magnesium.
OMg!
Wasn't it dating sodium?
O? Na.
I loose the ability to breath oxygen when i see you, Olivia
Nic3
Good shape 👌
YASSSSS MISS OLIVIA!!!!! THIS NON GLASSES LEWK!!!!😍😍😍😍😍😍
What about tapeworms and other parasites?
When looking for life on other planets wecneed to broaden our search
That's what always gets me. I know they seem to focus on planets like ours for life but there must be many other types of life that was created and thrives on other elements. Hell I'm sure there's a ton of elements out there that we have no clue about that also supports life.
@@rsw0103 The thing is, how he heck do you look for things you don't know what it looks like? It's easy to look for earth-like life since we have an example of that.
@@swedneck Oh I know that's the reason scientists look for life like ours but I'm just saying to think that there's no possible way life thrived in other conditions than life on Earth has lived in is most definitely a wrong way to think.
The first steps for looking for extraterrestrial life is to look for water and distinguish between rocks and not-rocks
I'm pretty sure that covers most of what we'd be able to find, unless there are some rock-like organisms out there
@@zeppie_ I get that. We know water helps creating life in THIS galaxy but I highly doubt that's a fundamental rule in the whole universe. Maybe instead of water a new combination of elements helped life evolve from a special type of primordial ooze.
Earthlings are going to be considered weird tho.
"They all breath fire fuel"
Huh, why does this feel like a re-upload?
You sound like you are going to fall asleep.
Hope you're well though
Something looked different and it took me way too long to realize what. XD
No glasses! Lol she looks really good without them
yay Oliva is back :) how's baby doing?:)
"Life finds a way "
Anton Petrov was first in making a video about this. Yay!!
You could say they were... empty of DNA
🤔 does it have a symbiotic relationship with an anaerobic bacteria in side it. It actually seems more strange to me that we have not found more like it yet.
What about that strange ecosystem in the middle of atlantic around those hydrothermal chimneys???
You probably mean the hydrothermal vent worms. I guess they need oxygen too..
A lot of the extremophiles there aren't animals bu bacteria. The animals present have mitochondria and DO siphon oxygen from the water, as well as making use of other oxidizers like sulfate. They don't get much oxygen but can use it if it's there.
So wait, we find a new form of life that operates differently from us and our first thoughts are "how do we kill it?" Like I get that it lives in salmon but.. still.
There's always an exception.
