Thank you so much. Seriously I am impressed by how I learn more with a 15 minute video, than what I learned in a whole semester of biochemistry in med school.
Khan Academy you should produce the big flow diagrams present on the videos (like this one) as downloadable PDFs for us to download, they're really useful!
So basically ETS and oxidative photophosphorylation are one and the same or The oxidative photophosphorylation is just a part of the ETS!! Thanks KHAN ACADEMY!!
Nice demonstration. 2 questions 1) how does the matrix acquire all of those protons ( that later get transported )? 2) how does the oxygen molecule get inside the matrix?
Which of the videos directly precedes this particular one? Specifically which one explains the output of the 4 ATPs, 10 NADHs & 2 QHs as shown on the top right of this presentation in purple. I might assume if I was to watch them in order it would be 1) Steps of Glycolysis, 2) Krebs/Citric Acid Cycle, 3) Oxidative Phosphorylation 4) Electron Transport Chain ???????? Thanks.
Thank you so much Mr. Khan, my lord, savior, and personal baby jesus. May you be blessed with all of the ATP synthases that you could ever want. (I could tell you really love them!)
oxidative phosphorylation Is the process of creating ATP by reducing oxygen. Oxidative phosphorylation occurs on the electron transport chain. So basically, the ETC is the site of oxidative phosphorylation.
Loved how he explained "hydrogen proton" without even thinking about it... like thats not enough information that someone has to check the textbook for. Lol
actually in the electron transport chain ,the H+ ions used in the reaction for oxidation of O2 is one and the same reaction here with 2H+ ions is two...can i get any explaination
could you solve a case were these is something wrong with the mitochondrian which leads to a person not walking, sitting, talking. Basically entire body does not function. I am looking for someone who can look at this case because they can not find what the problem is! they now the 'pump' in the mitochondrian is not working.. but they do not know why. We can not proceed if this is not find! please any help means the world
About 28 ATP are produced by oxidative phosphorylation per starting glucose. Adding the 2 net ATP from glycolysis and the equivalent of 2 ATP from the citric acid cycle, the total ATP per glucose for all of cellular respiration is about 32 ATP. The older values of 36 ATP or 38 ATP are now outdated.
I'm going into the Sixth Grade and I need you help. Well in summer your supposed to do a math packet. I'm on basically the last page but I have no idea how to do this one problem. This is is " 10= 2/3 x _____ and you have to answer the blank. If you can please make a video on how to do it. In. A couple days it's going to be school and I have to finish it. Thanks :)
+Antonella Melillo Hi Antonella, First set up the equation where x is the unknown number to find: 10=2/3x Next, multiply both sides by 3: 30=2x and now finally divide both sides by 2: 15=x and so 15 is your answer :)
+Krin rin H2O is a byproduct of cellular respiration. O2 is the final acceptor because it's the last chemical species to accept the electrons, after the complexes. When it accepts the electrons, it becomes water.
maybe you just have a weak biology foundation? that's what I found out, my lack of simple biology knowledge (as a chemistry major) made biochem more annoying then it otherwise would be. But it's a cool subject if your objective about it
I love Biochemistry and Biology in general. It gets a lot better when someone explains it clearly. Love science man
I don't get why professor get paid so much to teach so little while this guy just taught me everything in 15mins...
Cause he or she in the first place is a researcher, not a teacher.
thats right, good researcher doesn't mean good teacher. I think that some people have forgotten that.
They typically don't get paid "so much"
@@DahenKike You are the one who is pretty st*pid here. Don't you know how to respect to teachers? Oh sorry, I mean "Medicine teachers(!)."
Love how passionate he gets about the ATPase as a rotary motor lmao
Well it is cool tbh; the smallest motor in the known universe
"It's not some abstract thing that's separate from your reality!" . When he says stuff like that it makes the lesson memorable XD.
If only more teachers were that passionate.
if only i could go and get the government to send my uni payments to you.. thanks for my first year biochemistry module!
I wish I could just do online high school and watch khan academy videos and finish two years early
Your wishes have been heard
@@cinnamonbun216 LMAOOOOO
this aged so badly

Biochem final in 1 hour let's gooo
Same here bestie how did it go for you
I.....I understand. I UNDERSTAND
nasam jajou literally me rn😂😂😅
why is that me😂😂
That is me literally
I can't believe someone can teach you this much in so little time.Thanks for everything,you really helped me!!
this guy makes anything sound exciting; i actually stood awake, thank you!!
More professors/teachers like you are needed. The amount of knowledge you have is the reason your lessons are clear and extremely comprehensible
wow, your enthusiasm made me actually enjoy biochem... :D keep it up
THANK YOU. YOU ARE LEGENDAIRY. THANK YOU. I WAS ACTUALLY INTERESTED. YOU INTERESTED ME. 😱 THANK YOU! And I understand it now.
legenDAIRY
I have my bio234 final next week and this video just saved my life. Thank you!
This helped me so much with my cell bio exam. Thank you!
This was so brilliant, everything makes so much sense now

+randombadger41 Seconded. Sometimes I just recreate them myself, but it's a stupid amount of work.
I was about to say this actually I want the whole thing in pdf so i can look it over its so nice
I agree!
TheProteanGirl you can just take a screenshot and then look at it in your gallery
Well actually there r a few images like these (with white background so u can print it) on his khan academy app or website. :D
This was a truly excellent overview, thank you.
Has Sal won an educators award? He should
I love y'all. I was becoming extremely frustrated, but FINALLY, a video that held my hand !!!😊
Thank you so much for making a pretty difficult subject actually so easy!
So basically ETS and oxidative photophosphorylation are one and the same or The oxidative photophosphorylation is just a part of the ETS!! Thanks KHAN ACADEMY!!
Thank you very much for explaining this stage in so much detail!!
Where was this when I was studying for my biochemistry final?!?!
+Media Luna hahaha ikr
Nice demonstration. 2 questions 1) how does the matrix acquire all of those protons ( that later get transported )? 2) how does the oxygen molecule get inside the matrix?
Wow what a legend.Ur amazing.thank u
and it was that simple.....thank you so much sir
This video low key got me hyped

thank you for saving my life and my exam grade
You're a life saver!
Khan Academy is really useful
Thank You for your explanation.. it's helps a lot...
this is like my life fucking saver. actually, all of his videos are. this dude is fucking god
thanks for such vivid explanation
This is beautiful. Thank you 😊
this saved me thaaaaank you
Excellent. Thanks for making it much easier to understand 💐🙏🏼
Excellent video--thank you!
Thank you so much Sir!
Thank you so much Mr. Khan, my lord, savior, and personal baby jesus. May you be blessed with all of the ATP synthases that you could ever want. (I could tell you really love them!)
thank you so much for explaining so well 😍
That is very helpful thanks ❤️🌹
Thanks a lot, amazing work!
biochemistry is finally understandable
*watches this video*. 2 min later " knowledge is power"
Perfectly Explained! Thank you :)
Thank you sir
Loved it, subscribed.
thanks!
Thank you.
khan is the best khan
PRAISE G-D,
ALL HAIL KING KHAN!
THANK U
just Awesome
In the cell does it take ATP to get ATP in this process?
awesome videooo ^^
thank you :)
i just wish i understand how do they know all this is happening....im mind blown
They prepare first
2:50 my thoughts during exam
youre a scientist in the functioning of the matrix you legend
Guys I UNDERSTAND!!!
Mitochondria is the powerhouse of the cell
Awesome
Is Mr.Khan even a real person? It’s just seems so unrealistic to me that he had helped a lot in a wide range of subjects.
Whats the difference between oxidative phosphorylation and electron transport chain?
yup same question here:-?
oxidative phosphorylation Is the process of creating ATP by reducing oxygen. Oxidative phosphorylation occurs on the electron transport chain. So basically, the ETC is the site of oxidative phosphorylation.
Does the electron transport chain require ATP to make it?
Loved how he explained "hydrogen proton" without even thinking about it... like thats not enough information that someone has to check the textbook for. Lol
actually in the electron transport chain ,the H+ ions used in the reaction for oxidation of O2 is one and the same reaction here with 2H+ ions is two...can i get any explaination
Where does the two electrons come from?
NADH -> NAD+ + H+ (+ 2e)
is it possible to use a half of oxigen molecule? or is just matematically?
yes, its just simplification
Can someone please explain why the oxidation of coenzymes such as NADH causes hydrogen protons to be pumped into intermembrane space? Thanks!
what program is this?
could you solve a case were these is something wrong with the mitochondrian which leads to a person not walking, sitting, talking. Basically entire body does not function. I am looking for someone who can look at this case because they can not find what the problem is! they now the 'pump' in the mitochondrian is not working.. but they do not know why. We can not proceed if this is not find! please any help means the world
During oxidative phosphorylation, what is the net ATP production, assuming two ATP molecules are consumed during the process?
About 28 ATP are produced by oxidative phosphorylation per starting glucose.
Adding the 2 net ATP from glycolysis and the equivalent of 2 ATP from the citric acid cycle, the total ATP per glucose for all of cellular respiration is about 32 ATP. The older values of 36 ATP or 38 ATP are now outdated.
When you skip to the last 10 secs of a Khan video to get the complete notes and your brain explodes.
Test coming up
By looking at diagram itself am totality fused...
IS Oxidative phosphorylation and the electron transport chain the same?
Taiwo oladimeji yes

That helped me so much
Antonella Melillo No problem, happy to help!
starting itself is making me to faint
If 10 NADH and 2 FADH2 were formed, why weren’t 12 water molecules produced
What is H20 for? And what makes oxygen as the final acceptor?😸😸
+Krin rin
H2O is a byproduct of cellular respiration.
O2 is the final acceptor because it's the last chemical species to accept the electrons, after the complexes. When it accepts the electrons, it becomes water.
it's d bst academy I guess😀
How can this guy know so much?
Electron*
I'm out thats to complicated for 9th grade..
DONATE TO KHAN ACADEMY TO KEEP THEM FREE !!!
I hate biochem!!!!
Why are you guys studying it then though?
What course are you doing?
You probably hate this cuz u dont understand. If you learn it, it becomes easy and pleasuring.
maybe you just have a weak biology foundation? that's what I found out, my lack of simple biology knowledge (as a chemistry major) made biochem more annoying then it otherwise would be. But it's a cool subject if your objective about it
