Glycolysis:
Glycolysis is the first step in cellular respiration and occurs in the cytoplasm of the cell. It involves the breakdown of one molecule of glucose (a six-carbon sugar) into two molecules of pyruvate (a three-carbon compound). During glycolysis, ATP and NADH (a coenzyme) are produced, and some ATP is consumed. The net gain of ATP in glycolysis is two molecules of ATP per molecule of glucose. Glycolysis can occur under both aerobic and anaerobic conditions. If oxygen is available, pyruvate is further oxidized in the citric acid cycle and electron transport chain as part of aerobic respiration. If oxygen is lacking, pyruvate may undergo fermentation to generate ATP.
