Detailed explanation-1: -Glycolysis is the metabolic pathway that converts glucose into pyruvate. During glycolysis process, 2 ATP molecules and 2 NADH molecules are produced. FADH is not produced during glycolysis.
Detailed explanation-2: -The reactant is glucose and the products are molecule of pyruvate, 2 ATPs and 2 NADH.
Detailed explanation-3: -Explanation: Oxygen is neither a product nor reactant in glycolysis. Glycolysis is unique in that it takes place within the cytoplasm of the cell and does not require oxygen. It is an anaerobic reaction that produces pyruvate, NAD, and ATP.
Detailed explanation-4: -Answer and Explanation: Glycolysis is the first stage of cellular respiration, and the reactants are one molecule of glucose and two molecules of ATP (adenosine triphosphate).
Detailed explanation-5: -Explanation: Pyruvate is the end product of glycolysis. After glycolysis, the three-carbon molecule pyruvate is converted into the two-carbon molecule acetyl-coenzyme A (acetyl-CoA). This is carried out by a combination of three enzymes collectively known as the pyruvate dehydrogenase complex.
