What major events happen in glycolysis?

Glycolysis is a metabolic pathway that converts glucose into pyruvate, generating a net gain of two ATP and two NADH molecules. The process occurs in ten enzymatic steps, starting with the phosphorylation of glucose to glucose-6-phosphate, followed by a series of transformations that eventually split the six-carbon molecule into two three-carbon pyruvate molecules. Key events include the investment phase, where ATP is consumed, and the payoff phase, where ATP and NADH are produced. Overall, glycolysis serves as a crucial energy-producing pathway in both aerobic and anaerobic conditions.
