Cellular Respiration Flashcards
1
Q
Where do H+ move during ETC vs chemiosmosis?
A
H+ move from matrix to intermembrane space vs intermembrane space to matrix via ATP synthase
2
Q
What’s chemiosmosis?
A
when ATP synthase makes ATP from ADP + Pi w/ H+ moving from intermembrane space to matrix
3
Q
How many ATP does 1 NADH vs 1 FADH2 make in ETC?
A
2.5 ATP vs 1.5 ATP
4
Q
Difference b/w Complex I vs II in beginning of ETC. Which one contributes to H+ gradient?
A
NADH enters, contributes to H+ gradient vs FADH2 enters
5
Q
Is ATP hydrolysis exergonic or endergonic?
A
exergonic
6
Q
Is NADH a byproduct of ETC?
A
No. NAD+ is, cuz NADH gave away H+ to proton gradient
