Verified step by step guidance1
Understand the process of glycolysis: Glycolysis is the metabolic pathway that converts glucose (a six-carbon molecule) into two molecules of pyruvate (a three-carbon molecule), producing ATP and NADH in the process.
Identify the main outputs of glycolysis: The primary products of glycolysis are two pyruvate molecules, a net gain of two ATP molecules, and two NADH molecules per glucose molecule.
Evaluate each option based on glycolysis outcomes: a) A net gain of four ATP per one glucose molecule is incorrect because the net gain is two ATP. b) Conversion of FAD to FADH2 does not occur in glycolysis; it is part of the citric acid cycle. c) Conversion of one glucose molecule to two pyruvate molecules is correct. d) Conversion of NADH to NAD+ is incorrect; glycolysis produces NADH from NAD+.
Focus on the correct transformation: Glycolysis specifically involves the conversion of one glucose molecule into two pyruvate molecules, which is a key step in cellular respiration.
Conclude with the correct answer: Based on the understanding of glycolysis, the correct result is the conversion of one glucose molecule to two pyruvate molecules.
