Question

During fast (anaerobic) glycolysis, one glucose molecule would be metabolized to form?

1) Two molecules of pyruvate
2) One molecule of pyruvate
3) Two molecules of lactate
4) One molecule of lactate

Answer 1

One glucose molecule is metabolized to two molecules of lactate during anaerobic glycolysis. This process also yields a net gain of two ATP and two NADH molecules per glucose molecule.

Step-by-step explanation:

During fast (anaerobic) glycolysis, one glucose molecule would be metabolized to form two molecules of lactate. This occurs when glycolysis breaks down glucose into two pyruvate molecules, which are then converted to lactate due to the lack of oxygen in anaerobic conditions. In the process of glycolysis, for each glucose molecule, the net gain includes two ATP molecules and two NADH molecules, in addition to the two pyruvate molecules that are subsequently converted to lactate.
