net 2 N A D plus , 2 A T P , 4 C O sub 2 , 2 F A D H

6 NADH, 2 ATP, 4 CO2, and 2 FADH2
6 N A D H , 2 A T P , 4 C O sub 2 , and 2 F A D H sub 2

net 1 NADH, 1 ATP, 2 CO2, 1 FADH2

Answer 1

The correct option that lists the products of the Krebs cycle (also known as the citric acid cycle) after 1 molecule of glucose has gone through it is:

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

This is because one molecule of glucose leads to two turns of the Krebs cycle (since one glucose molecule is converted into two pyruvate molecules), and each turn of the cycle produces the following net products:

- 3 NADH
- 1 ATP (or GTP, depending on the cell type)
- 2 CO2
- 1 FADH2

Therefore, for two turns (due to two pyruvates from one glucose), the totals will be:

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

So, the answer is **6 NADH, 2 ATP, 4 CO2, and 2 FADH2**.
