Detailed explanation-1: -The final product of glycolysis is pyruvate in aerobic settings and lactate in anaerobic conditions. Pyruvate enters the Krebs cycle for further energy production.
Detailed explanation-2: -Lactate is always the end product of glycolysis.
Detailed explanation-3: -Metabolism of pyruvate results in the formation of acetyl coenzyme-A as the chief end product. In fermentation, pyruvate is reduced to produce lactic acid or ethanol.
Detailed explanation-4: -Glycolysis starts with one molecule of glucose and ends with two pyruvate (pyruvic acid) molecules, a total of four ATP molecules, and two molecules of NADH.
Detailed explanation-5: -The end products of glycolysis are: pyruvic acid (pyruvate), adenosine triphosphate (ATP), reduced nicotinamide adenine dinucleotide (NADH), protons (hydrogen ions (H2+)), and water (H2O). Glycolysis is the first step of cellular respiration, the process by which a cell converts nutrients into energy.
