Glycolysis is a series of metabolic reactions that breaks down glucose molecules into pyruvate or lactate. During this process (glycolysis), energy is released.
The net result of glycolysis is 2 ATP molecules, 2 NADH molecules, and 2 pyruvate molecules (Option C).
In aerobic conditions, pyruvate molecules enter the Krebs cycle to produce more energy (i.e., ATP and NADH).
In aerobic conditions, the final product of glycolysis is pyruvate, but glycolytic reactions produce lactate in anaerobic conditions.
