If a cell produces on average 30 ATP molecules for each molecule of glucose that is completely oxidized to carbon dioxide and water, how many ATP molecules on average can the cell synthesize for each molecule of pyruvate oxidized to carbon dioxide and water?
A) 8
B) 12.5
C) 14
D) 25

Question

Quizplus · Accepted Answer

Each glucose molecule produces 2 pyruvate molecules. The complete oxidation of one glucose molecule yields 30 ATP, so each pyruvate yields half of that, which is 15 ATP. However, considering the energy cost of transporting pyruvate into the mitochondria, the net yield is approximately 12.5 ATP per pyruvate.
