Question

How many FADH2 molecules does the Krebs cycle produces per 3 glucose molecules?

Answer 1

One molecule of glucose is broken down into two molecules of pyruvate.

So the krebs cycle occurs twice for each glucose molecule.

In the krebs cycle 1 molecule of FADH2 is produced.

we multiply 3 molecules of glucose by 2 krebs cycles that occur

3*6=6krebs cycles

and 1 molecule ofFADH2 per cycle so we get 6 molecules of FADH2
