question:
How many ATP are produced from 2 molecules of glucose using only substrate level phosphorylation.
Kaplan Answer: 8
Kaplan explanation: Substrate level phosphorylation occurs when ATP synthesis is directly coupled with theta degradation of glucose without the participation of an intermediate molecule such as NAD+. Degradation of one glucose
molecule yields a net of 2 ATP from glycolysis and 1 ATP for each turn of the citric acid cycle. Thus a total of 4 ATP are produced by substrate level phosphorylation for one molecule of glucose. For two molecules, it would be 8 ATP.
My question is: If each turn of glycolysis produce 2 ATP and each turn of citric acid cycle produce 1 ATP by 1 molecule glucose, totally ATP counts should be 3, How Come the Answer is 8, not 6 by 2 molecule of glucose?? Thanks alot!
