Electron Transport Chain

Overview of the Electron Transport Chain

[andreagallegosdei]

imagine taking a semester class with this guy as your biology professor. Would actually be worth paying tuition.

newer concept states: 
1 NADH  provides 2.5 ATP
1 FADH2 provides 1.5 ATP
therefore by the end of cellular respiration 32 ATPs are formed

Thank you!! I love these videos; they help so much! Khan academy is more useful than my $300 textbook

THIS. NOW THIS is how a lecture should be taught. I'm so sick and tired of all my professors reading dully off of powerpoint slides. No explanation, no excitement, and it isn't even put in the lecturer's own words, making it harder to convey the full message. You have taught me ALL of the key points for aerobic catabolism when it took me 4-1 hour lectures and 3 hours of my own time reading through the book and sorting through all of the overwhelming information.

[khanacademy]

I agree. That's a classy "first". I am proud that Khan Academy viewers are this sophisticated :)

[Jessica-ifzv]

I don't normally comment, but holy shit Khan Academy thank you so much.

[gbeepee]

I remember watching this in AP biology in high school and now I'm taking biochemistry during my last summer of my biological sciences degree. Thanks Khan! You've been with me the whole time.

This takes "The mitochondria is the powerhouse of the cell" to a whole new level.

[jakigotowiga]

.Are there any plans underway to award Khan Academy a Nobel Prize or something.??just curious.

[hotsummer]

im taking a biology test next week. thanks khan academy.
i sometimes regret i should rather have paid attention to professor than cram for an exam but i never put it into action :)

How in the world are you supposed to comprehend this in one sitting? It's like there is a component within a component within a component within a component within a component. And each one of those components has multiple pieces in of themselves. I lose context very quickly with each step being explained. You are very blessed with a good mind if you can understand all this in one sitting.

I am in an introductory Microbiology class and I cannot explain to you how much all of these videos have helped me. I DEEPLY appreciate you taking the time for this because I feel prepared for my test now when I thought all hope was lost. THANK YOU SO MUCH!

[FamineNH]

Thank you so much for these videos bro. I had my midterm this week over cellular respiration, photosynthesis, and cellular membranes. I read all the chapters in my textbook, but they were so complex I was having a hard time grasping it. Ended up watching your videos on each of these subjects all night before my exam and I got a 98! Almost half of the class failed the midterm and only 2 other people got As. You seriously explain things so well in a way that is very easy to grasp and remember. Thanks a ton <3

Sal: i'm not gonna go into detail on this.
*goes in detail*
And the amazing thing, I understood it all

Nice video, slight correction: protons are pumped into the intermembrane space, they are not pumped into the outer membrane.

Khan Academy is truly a life saver. This year when I embarked on my journey through AP biology I was really nervous because it's my first year of high school. However, by watching his videos and reading in my textbook I feel confident in my understanding of complex concepts and I have really come to love biology. Each day I'm one step closer to becoming a doctor ! Also, I'd just like to point out that khan academy isn't meant to give you the run down of an entire chapter in one 17 min video. It is essential that you read, listen in class, work on schoolwork at home, and then review. Ps: to the person who asked what the difference between chemiosmosis and the ETC is, chemiosmosis is the process of the atp synthase working within the electron transport chain. These two combined are known as oxidative phosphorylation. :))))

[indraalagar]

Before this video the ETC seemed so complicated- now after watching it I actually understand how it works!  Khan's concise explanations really cleared up those 6 or so pages in my AP Bio textbook.  Thanks Khan Academy for making biology so enjoyable and easy to understand!! 

[aisharazi]

how can i understand 17 mins video over 1 our lecture at college? KHAN ACADEMY YOU ARE MY SAVIOUR. My soul flew out of my body when you said the protons wants to go back in haha

[juicydior]

Khan Academy saves my life every time it has to do with math or biology! This amazing video for ETC clarified many things for me. Basically a one on one session with a much knowledgeable person! Great job.

I love it when he says "this is...THE CUTTING EDGE"
