In a human red blood cell, one round of glycolysis produces a net gain of 2 ATP molecules. The overall chemical reaction equation for glycolysis is:C6H12O6 glucose + 2 NAD+ + 2 ADP + 2 Pi 2 C3H4O3 pyruvate + 2 NADH + 2 H+ + 2 ATP + 2 H2OHere, NAD+ is nicotinamide adenine dinucleotide oxidized form , NADH is nicotinamide adenine dinucleotide reduced form , ADP is adenosine diphosphate, Pi is inorganic phosphate, and H2O is water.
