6 NADH, 2 ATP, 4 CO2, and 2 FADH2

Answer 1

The correct option for the products of the Krebs cycle after one molecule of glucose goes through it is:

**6 NADH, 2 ATP, 4 CO2, and 2 FADH2.**

Here's a brief explanation:

When one molecule of glucose is metabolized, it is converted into two molecules of pyruvate during glycolysis. Each pyruvate molecule enters the Krebs cycle, resulting in two turns of the cycle for each glucose molecule. Each turn of the Krebs cycle produces:

- 3 NADH
- 1 FADH2
- 1 ATP (or GTP)
- 2 CO2

Thus, for two turns of the Krebs cycle (one for each pyruvate), the totals become:

- 6 NADH (3 per cycle x 2 cycles)
- 2 FADH2 (1 per cycle x 2 cycles)
- 2 ATP (1 per cycle x 2 cycles)
- 4 CO2 (2 per cycle x 2 cycles)

Therefore, after one glucose molecule goes through the Krebs cycle, the net products are **6 NADH, 2 ATP, 4 CO2, and 2 FADH2.**
