The correct response regarding the products of the Krebs cycle after 1 molecule of glucose goes through it is:
6 NADH, 2 ATP, 4 CO2, and 2 FADH2
This is because one glucose molecule, after being converted to two molecules of Acetyl-CoA (which are each processed in the Krebs cycle), ultimately yields:
- 6 NADH
- 2 ATP
- 4 CO2
- 2 FADH2
Thus, the first option is the correct one.
