To determine the products produced when one molecule of glucose undergoes glycolysis, we need to understand the process of glycolysis. Glycolysis is the first stage of cellular respiration and occurs in the cytoplasm of cells. It involves the breakdown of one molecule of glucose into two molecules of pyruvate.
During glycolysis, a series of enzymatic reactions occur that result in the production of ATP, NADH, and pyruvate.
Let's break down the options:
1. 3 NADH and 1 FADH2: This option is incorrect as FADH2 is not produced during glycolysis.
2. 1 ATP, 3 NADH, and 1 Pyruvate: This option is correct. Glycolysis produces a net gain of 2 ATP molecules directly and 2 NADH molecules through the conversion of NAD+ to NADH. It also produces 2 molecules of pyruvate as the final product.
3. 2 ATPs, 2 NADH, and 2 Pyruvate: This option is incorrect as glycolysis produces a net gain of 2 ATP molecules, not 4 ATP molecules.
4. 4 ATPs, 6 NADH, and 2 FADH2: This option is incorrect as glycolysis produces a net gain of 2 ATP molecules, not 4 ATP molecules, and it does not produce FADH2.
Therefore, the correct answer is "1 ATP, 3 NADH, and 1 Pyruvate."
