Detailed explanation-1: -The correct answer is (E). The three-carbon molecule that is the final product of glycolysis is pyruvate.

Detailed explanation-2: -Pyruvic acid is the end product of glycolysis. Two molecules of pyruvic acid are generated by the partial oxidation of one glucose molecule.

Detailed explanation-3: -1: Glycolysis produces 2 ATP, 2 NADH, and 2 pyruvate molecules: Glycolysis, or the aerobic catabolic breakdown of glucose, produces energy in the form of ATP, NADH, and pyruvate, which itself enters the citric acid cycle to produce more energy.

Detailed explanation-4: -The breakdown of glucose, a six-carbon molecule, into a three-carbon molecule called pyruvate takes place in the cytoplasm.
