Expert Answer:

Glycolysis is a metabolic process (consisting of a series of biochemical reactions), in which glucose is broken down to pyruvate with the release of ATP.

One molecule of glucose undergoes two phosphorylation reactions and is then split to form two triose-phosphate molecules. Each of these is converted to pyruvate. The net energy yield is two ATP molecules per glucose molecule. In aerobic respiration pyruvate then enters the Krebs cycle. Alternatively, when oxygen is in short supply or absent, the pyruvate is converted to various products by anaerobic respiration
