So, we know that plants use sunlight to make food. That’s kind of one of the most important facts in our ecosystem. Plants and photosynthetic bacteria form the bedrock of our food chain and are one of the most important forces making Earth a habitable planet.
But--how do we transition from solar energy to chemical energy? How exactly do plants store sunlight once it’s been captured? This requires one of the most important journeys on earth. In this video, we’ll take a trip down the electron transport chain in chloroplasts and see how cytochrome bf, plastocyanin, photosystem I, and ferredoxin work together to create the power necessary to make food from sunlight.

It’s cool that sunlight becomes food during photosynthesis--but how do plants convert solar energy into chemical energy? Find out in part 2 of our 4-part series on photosynthesis. We're going to explore how Photosystem 2, Cytochrome Bf, plastoquinone, photosystem 1, and ferredoxin work together to move electrons. We'll see how we can use those electrons as bait to bring more protons across the thylakoid membrane and into the lumen. From there, we'll see how Photosystem 1 excites electrons and helps them complete their journey by making NADPH.
All this motion takes the energy of sunlight and helps convert it into chemical energy.
So unbelievably unfortunate that a channel with this kind of quality production and clarity of explanation only has like 12k subscribers and hasn’t posted in 2 years. I truly wish your videos reach the right audience at some point and you get the success you deserve
Season 2 comes out soon based on community posts!
This guy was AMAZING !!
I absolutely loved the series - i will donate $50 if the guy drops a comment below my comment ❤❤
Thank you Clockwork !
I can't believe how good this channel is, I really can't.
Sameeeee
Thanks John Green for introducing me to this channel. What a joy it is!
Welcome! I'm really glad the work is able to connect with folks.
I'm very sad your channel hasn't uploaded in so long.
You make incredible content.
"Charge works just like a magnet" has Lorentz laughing somewhere.
I am always so jealous of your animations - great vid!!
oh no-- I am WAY more jealous of your ability to actually put a video out every week. And of the clarity with which you discuss the topics you research. But--either way, I'm excited that we're growing together! Congrats on 100 videos!
@@Clockworkbio Thanks!! And likewise, maybe in the future we should try and arrange a collab - think that would be cool! 😊
I think that would RULE. I already had a few ideas for a collab--but I was worried that I blew my shot by making such a terribly shallow video on telomeres and senescence earlier this year. I'll hit you up on DIscord/ Twitter with a few ideas? Feel free to throw any ideas at me too if you've got them!
@@Clockworkbio cool, twitter is best!
I was just trying to learn photosythesis, but after watching these photosythesis videos obsessively and some of the others I can't wait for the return if the G in June. This cat knows how to explain stuff, and make it look pretty and be inspiring.
of?
I really like how you're creating multi-episode series while making it so that each video can also be stand-alone! And of course, you're doing a really impressive job at getting these videos out consistently haha. Great job as usual- you're getting really close to 1000! :)
DUDE--I'm so happy to see you in my comment section! It's been a minute! Congrats on making to 1k yourself. Got a new video coming out on the horizon or are you more focused on coursework and all that?
Good stuff mate keep up the hard work!
Really amazing video.
I came here from the new vlogbrothers video, and I couldn't be more thankful that they recommended you. I am a big (BIG) sucker for science, especially biology, but I was never good enough to actually go into it as a major, but because I was good enough, I was able to major in psychology. My passion and curiosity for science are still there, waiting to be nourished, so I dedicate my free time to indulge in my guilty pleasure, and I look for simple yet interesting and entertaining ways to learn (it's my free time, after all). I fell in love with this channel, you are so underrated, I hope other people get to see that as well!!!!
Love these videos for all the good reasons.
This IS BRILLIANT! Thank you 👍💕😁🙏
Thanks so much for the lovely sentiment--especially saying something so nice on what is objectively the most boring video I ever made!
Amazing video 👍
Very cool indeed. Will watch all video's.
Wow So cool. I love your channel and wish you the best.
Thank you so much for this summary! As fascinating as they are, plants are definitely my least studied eukaryotic kingdom and so I'm really missing some of this foundational biochemistry despite how incredibly crucial it is to literally every other member of Eukarya. While I do remember learning some of this, it rapidly became swamped by mammalian biochemistry and so it's wonderful to have it all recapped and a few new things added on as well. Had no idea just HOW oxidising the P680/P700 complexes are!
I think my main question for my own further reading: how do the different forms of chlorophyll convey different advantages? Chlorophylls A through E (A being the most common and found in all known photosynthetic life) each seem to have different use-cases. I wonder how each of them interact with each other (given that many cells have multiple types) to convey different advantages over using chlorophyll A alone!
In the same way that these complexes partner up to convert sunlight into chemical energy, My channel would be not NEARLY as high quality without the support I get from my partners over at Biocord. Check out the best life sciences community on discord here: discord.gg/kwsVbfC
What are the differences between CoEnzyme Q (in oxidative phosphorylation) and Plastoquinone? I can't help but get the impression they're almost the same as they both take two electrons and transfer them to a cytochrome. Thanks in advance.
I have a question in this, but before that, I would really like to appreciate your effort and interest in this field
I’m begging you. (Oh by the way thank you for your series on ADT synthase! 👍 )
Where was I… Oh yeah: I’m begging you: Please oh please try to go one layer deeper on how the electrons know where to go. I’m most interested in the Krebs cycle, especially in reverse, but I’ll take whatever you wanna do…. The Calvin cycle is excellent and I’ll happily follow along there, too. But cancer sounds really weird, in biochemical terms. 😮
…That’s all I’ve got right now.
Either way (obviously I have no idea what I just asked of you!) please keep doing this TH-cam thing! Awesome!
One day, I thought it was weird that there’s this trope in literature about how bumblebees can’t fly, or don’t know they can’t fly, or something similarly silly. So I looked up bee muscles because I figured they had to be different. 🤯🤯🤯
😵💫 You know exactly what happened to my brain after that! Next thing you know I’m looking at the differences between airplane lift vs bee lift, and then bug juice vs blood, and then I got “biochemistry for dummies” and learned how dish soap works…. Nowadays, I’m expecting Severus Snape to pop up as a caterpillar that talks about muchness, and then turns into The English Patient. (I’m not at all confused about my Kevin Bacon movie linkage. Rather, I’m trying to explain the effect biochemistry has had on my curiosity.) Your animations are fantastic! 👍 May I have some more please?
like this one❤
Very very cool video's I only discover now. Why did you stop making them?
I needed to make the transition to 3d so I could better explore more topics. Took me longer than expected-but season 2 launches in June!
You kind of sound like the British guy from that video who calls a skaleton a cadaver
miss ya
I'll be home soon
So, we know that plants use sunlight to make food. That’s kind of one of the most important facts in our ecosystem. Plants and photosynthetic bacteria form the bedrock of our food chain and are one of the most important forces making earth a habitable planet.
My question is that if the p860 and p700 are positively charged then why do they transport the electrons to the other parts instead of absorbing them???
They're only positively charged from the subsequent transfer of electrons; they're positive because they've just donated that electron. They can only absorb electrons from another molecule where it is energetically preferable or feasible, no take-backs.
Isn't it Veritasium voice???
Yt should be sued for not having this on everyone’s recommend page
Where is the photon????
hank? is that you?
ahh yes. 0 Dislikes as it should be
Which is weird because this is like--the most boring and tedious video I ever made! The harder you work to watch your way through a video--the more you'll end up liking it, I guess?
@@Clockworkbio Boring? I have no need to understand this. I'm watching this purely for entertainment! :D
@@dannytbm same
So when do we get to PS 5? I hear that's all the rage these days.
Hopefully we will soon! But I think we can all agree that PS II is the best and has been impossible to top.
