What happens during glycloysis in celluar respiration?

Glycolysis is the first step of cellular respiration, occurring in the cytoplasm of the cell. During this process, one glucose molecule is broken down into two molecules of pyruvate, producing a net gain of two ATP (energy) and two NADH (electron carrier) molecules. The process involves a series of enzymatic reactions that convert glucose into intermediates and ultimately pyruvate, while also releasing a small amount of energy. Glycolysis is anaerobic, meaning it does not require oxygen.
