Final answer:
The correct end products of glycolysis are A. pyruvate, ATP, and NADH, as glycolysis converts glucose into pyruvate and produces a net gain of two ATP and two NADH molecules.
Step-by-step explanation:
The end products of glycolysis are: A. pyruvate, ATP, and NADH. Glycolysis is a metabolic process that converts glucose into two molecules of pyruvate. During this conversion, the cell makes a total of four ATP molecules, but since two ATP molecules are used up in the initial stages of glycolysis, there is a net gain of two ATP molecules. In addition to ATP, glycolysis also produces two molecules of NADH, which can be used for generating more ATP in the mitochondria. Therefore, the correct answer to the question is A. pyruvate, ATP, and NADH.
