4 ATPs, 6 NADH, and 2 FADH2
3 NADH and 1 FADH2
3 NADH and 1 FADH2
2 ATPs, 2 NADH, and 2 Pyruvate
1 ATP, 3 NADH, and 1 Pyruvate
If one molecule of glucose undergoes the reaction of glycolysis, the correct response is:
1 ATP, 3 NADH, and 1 Pyruvate
To determine the products of the glycolysis reaction, we need to understand the process of glycolysis. Glycolysis is the initial step in the breakdown of glucose, and it occurs in the cytoplasm of cells. During glycolysis, one molecule of glucose is converted into two molecules of pyruvate.
Let's analyze the options given:
1. ATP, NADH, and Pyruvate: This option is the correct answer. During glycolysis, one molecule of glucose produces 1 ATP, 3 NADH, and 1 pyruvate.
2. ATPs, NADH, and FADH2: This option is incorrect. Glycolysis does not produce FADH2. Additionally, the number of ATPs and NADH molecules mentioned here is incorrect.
3. NADH and FADH2: This option is incorrect. Glycolysis produces ATP and pyruvate, in addition to NADH.
4. ATPs, NADH, and Pyruvate: This option is incorrect. The number of ATPs mentioned here is incorrect, and glycolysis also produces NADH.
Therefore, the correct answer is option 1: 1 ATP, 3 NADH, and 1 pyruvate.
