Cell respiration Flashcards
1
Q
Link reaction
A
Pyruvate enter mitochondria, converted to Acetyl CoA, releasing CO2 and NADH
1
Q
Glycolysis
A
Glucose broken down, 2 molecules of pyruvate
2
Q
Kreb’s cycle
A
Acetyl CoA enters cycle, producing NADH, FADH2, ATP, and CO2 in matrix
3
Q
ETC
A
NADH and FADH2 donate electrons to ETC. As electrons move through the chain, energy is released and used to pump protons across membrane
4
Q
Chemiosmosis
A
The protons pumped into the intermembrane space create a gradient. The gradient drives protons back into the matrix through ATP synthase
5
Q
Oxidative phosphorylation
A
As protons flow through ATP synthase, ADP is phosphorylated to ATP
