Wow! Look at the proton gradient in the river!
And now, for the final stage, the electron transport chain! We are at the H+ river on the Mitochondria christae to observe this
Are we going to get out and see the ATP synthase turn to attach a phosphate to ADP to make ATP?
Yes we will! Time to go see the process up close!

34-36ATP!!

Woah! Standing on the outer membrane of the mitochondria sure is weird

Tell me about it. But look, its all the NADH's we have seen along the way
NAD+

Yup! They send their H+ through the ETC to the intermembrance space to match the proton gradient

Cool! I can then see it pass back across the inner membrane into the Mitochondria Matrix

ATP Synthase

Yah! I can see the matrix field we were just at beyond this river

And as it crosses that membrane, it turns the ATP synthase, attaching a phosphate to ADP to make the 34-36 ATP!

I hope you liked the journey on the train that let us travel to the Cytoplasm to the Mitochondria Matrix to the Mitochondria Cristae.
I thought it was cool to watch Glucose turn into Pyruvate acids and then into Acetyl Co2 and then to see all the NAD+'s find their H+'s in the krebs cycle
And I thought it was cool to see all the NADH's finally show up at the ECT and deposit their H+'s. I also thought it was cool how the H+'s were used to spin the ATP synthase to make a whole bunch of ATP. Also glad to see the 2 ATP from the glucose breakdown factory show up at the end to make a net gain of 34-36 ATP.
