검증된 단계별 안내1
Understand the process of glycolysis: Glycolysis is the metabolic pathway that converts glucose (C6H12O6) into pyruvate, releasing energy and reducing power in the form of ATP and NADH.
Identify the inputs and outputs of glycolysis: The main inputs are one molecule of glucose, 2 NAD+, and 2 ADP + 2 Pi. The outputs are 2 pyruvate molecules, 2 NADH, and 2 ATP (net gain).
Recognize the role of NAD+ and NADH: During glycolysis, NAD+ is reduced to NADH. This means that for each glucose molecule, 2 NAD+ are converted to 2 NADH.
Calculate the net ATP production: Glycolysis produces 4 ATP molecules, but 2 are used in the initial steps, resulting in a net gain of 2 ATP.
Summarize the net products of glycolysis: From one molecule of glucose, glycolysis results in the production of 2 NADH, 2 pyruvate, and 2 ATP, which matches the correct answer provided.
