How many net molecules of ATP are generated per molecule of glucose oxidized via anaerobic glycolysis to lactate?
Answer and explanation
Correct answer: C. 2 net ATP molecules
Glycolysis consumes 2 ATP (hexokinase and PFK-1 steps) and produces 4 ATP (phosphoglycerate kinase and pyruvate kinase steps), yielding a net gain of 2 ATP per glucose under anaerobic conditions.
