During a glycolytic pathway, a glucose molecule is enzymatically degraded, producing either 2 pyruvates (in aerobic type) or 2 lactate (in anaerobic type) as the major product, 2 ATP (adenosine triphosphate) molecules, 2 NADH (Nicotinamide adenine dinucleotide), 2 water molecules, and 2 protons (H +).Figure 6.3.2: Step 1 of Glycolysis Figure 6.3.3: Step 2 and 4 of Glycolysis. The addition of the phosphate sometimes conceals the oxidation that occurred. G3P was an aldehyde. 1,3 BGP is an acid esterified to a phosphate. The two phosphates in the tiny 1,3BPG molecule repel each other and give the molecule high energy.The combined end product of glycolysis is two molecules of pyruvate per molecule of glucose entering the process, plus two molecules of ATP and two of NADH, a so-called high-energy electron carrier.
