How does glycolysis start
WebSep 6, 2024 · Glycolysis is the name for the series of reactions that takes place in all cells, prokaryotic and eukaryotic, to break down the six-carbon sugar glucose into two three-carbon pyruvate molecules. It occurs in the cytoplasm, does not require oxygen and results in the net production of two ATP. WebGlycolysis starts with glucose and ends with two pyruvate molecules, a total of four ATP molecules and two molecules of NADH. Two ATP molecules were used in the first half of the pathway to prepare the six-carbon ring for cleavage, so the cell has a net gain of two ATP molecules and 2 NADH molecules for its use.
