1.	When one molecule of glucose is oxidized to two molecules of lactate during anaerobic glycolysis, which of the following statements is false?(a) Glyceraldehyde 3-P dehydrogenase reaction produces 2 ATP molecules(b) Lactate dehydrogenase reaction produces no ATP(c) Pyruvate kinase reaction produces 2 ATP molecules(d) Phosphofructokinase-1 reaction uses 1 ATP moleculeI got this question in an interview for internship.My question is based upon Fates of Pyruvate under Anaerobic Conditions: Fermentation topic in section Principles of Bioenergetics and Glycolysis of Biochemistry
Answer» Correct choice is (a) GLYCERALDEHYDE 3-P dehydrogenase REACTION produces 2 ATP molecules To explain: When one molecule of glucose is oxidized to two molecules of lactate during ANAEROBIC glycolysis, Glyceraldehyde 3-P dehydrogenase reaction does not produce 2 ATP molecules.
