Correct answer: A). Glucose ; pyruvic acid
Glycolysis is the metabolic pathway that is known to convert glucose into pyruvate. The end product that is obtained after glycolysis is called as pyruvate, it can be further used in either anaerobic respiration or aerobic respiration. At the end of glycolysis, one glucose mole is broken into two molecules of pyruvate, ATP.
Hence, the correct answer would be option A.
