Cellular Respiration (Electron Transport Chain) 

Are you going to comment this on every electron transport chain RU-vid video? 2nd time today I see this same comment

@@alanzeblade928 those were the only two times I commented it

I don’t even remember I made this comment it was a year ago and I only did it twice so please don’t get mad at me

+group I agree, there is one more complex on which FADH2 releases its electrons.

+group But your ignoring the fact that this particular video was uploaded in 2008 not 2016

bro, this video was made 8 years ago..

Jaithen Williams no both are required

Everyone who is saying 8 years ago, we knew FADH2 was involved long before 2008.

Same here

+Reagan Nelson exactly. this is the only part of cellular respiration that i do not understand at all

+MizzBalleriffic23 Really? I'm more confused on the Krebs cycle.

+Sir Hadoken ha they don't even call it that they call it the Citric Acid Cycle

+Reagan Nelson +Reagan Nelson Don't know if this helps but here goes: What you want = ATP =energy = staying alive. So to make ATP we do the whole respiration thing to extract energy in glucose. This is done in a few steps, First Glycolysis, then Kreb's cycle, then Electron transport chain (What this video is about). We got 2 ATP from Glycolysis, 2 from Kreb's cycle. But that's really low, we need more. So we have this mechanism called Electron transport chain. It uses the stuff we got from Glycolysis and Kreb's cycle that's not ATP. They are molecules called NADH. They basically carry electrons, simple as that. So these NADH thingies go to this Electron transport chain and electrons are passed around as you see on the video between different proteins. The whole purpose of this is so that you can pump Hydrogen ions (H+) from inside the membrane to outside the membrane. (remember mitochondrion has 2 membranes? so the H+ stay in between the membranes they don't go outside). This creates lots of H+ outside compared to inside. And those Mofo H+ outside wanna get inside if you know what I'm sayin. So this creates a way for the cell to make energy using a turbine system called ATP synthase. This ATP synthase is just another protein that comes after this whole chain. but it acts quite literally like a turbine. When the influx of H+ ions try to get in, it spins the "machine" as they flow in and creates energy. This nets approx 38 ATP. To get a visualization of ATP synthase check the video on the recommended section called "Gradient(ATP synthase).

lmaoooo

YES IKR. I WAS KINDA SCARED SINCE IT REMINDED ME OF THE SAW

Are you alive?

Wow a seven-year-old comment here

now ur a doctor

@@Priyanka-zg9gj 😂

@@Priyanka-zg9gj 😂😂😂😂😂😂

Mee🙋🏻‍♀️....jus b4 exams

Same

Mee toooo

ok

Same HAHAHA

This still exist

Well, it has idealistically defined my test tomorrow.. 1 down. 2 more lessons to go. And it's midnight. Ugh.

welcome to biochemistry, my friend

IKR IT REMINDED ME OF THE SAW

Are you alive 😅😅😅

Are you a doctor now ?

Ya that’s how I learned it in grade 12 now and I’m like where the complex’s at

The IB brought me here as well. I feel like Respiration is the worst part of the entire Biology Syllabus! :(

Respiration and photosynthesis together, everything else is okayish!

I agree 100%. Are your exams in May 2014, too? :)

yup, what options you doing?:)

10 yrs ago omg are u alive?

From my understanding, it simply becomes FAD.. so NADH -> NAD- and FAD2 -> FAD
