Final answer:
Glycolysis is the process of breaking down glucose into pyruvate molecules. The net gain from the breakdown of a single glucose molecule in glycolysis is two ATP molecules, two NADH molecules, and two pyruvate molecules.
Step-by-step explanation:
Glycolysis is the process of breaking down glucose into pyruvate molecules. In this process, there is a net gain of two ATP molecules and two NADH molecules.
Glycolysis starts with one glucose molecule and ends with two pyruvate molecules, four ATP molecules, and two NADH molecules.
