Detailed explanation-1: -Explanation: The correct answer to this question is carbon dioxide. Carbon dioxide is not produced during glycolysis. Remember in glycolysis one glucose molecule yields 2 pyruvate, 2 ATP, and 2 NADH.
Detailed explanation-2: -Overall, glycolysis converts one six-carbon molecule of glucose into two three-carbon molecules of pyruvate.
Detailed explanation-3: -Pyruvate kinase is the enzyme involved in the last step of glycolysis. It catalyzes the transfer of a phosphate group from phosphoenolpyruvate (PEP) to adenosine diphosphate (ADP), yielding one molecule of pyruvate and one molecule of ATP.
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.
