The Energy Budget Flashcards
1
Q
In aerobic respiration how much ATP is made from glycolysis?
A
2 ATP are made overall and 2NADH formed make 3 ATP each so 8.
2
Q
In aerobic respiration how much ATP is made from the link reaction?
A
2NADH are made so 6.
3
Q
In aerobic respiration how much ATP is made from the Krebs cycle?
A
6 NADH and 2 FADH are made (6x3 and 2x2 = 18+4) and 2 are made on their own so 24.
4
Q
How many total ATP molecules are made in aerobic respiration?
A
38.
5
Q
Why is the cell generally not as efficient as the energy budget assumes in aerobic respiration?
A
- ATP is used to move pyruvate, ADP, NADH and FADH across the mitochondrial membrane
- proton leakage might occur across the membrane
- molecules also leak through membranes
6
Q
How many molecules of ATP are made in anaerobic respiration and why?
A
2, because there is no oxidative phosphorylation occurring.
