The "fuel" for the Kreb's cycle is

• CO2

• H2O

• GTP

• Acetyl-CoA

How many redox reactions does the cycle involves for a single turn?

• 1

• 2

• 3

• 4

The enzyme needed to catalyze Citrate into Isocitrate

• CO2 and H2O

• NAD+ and FAD

• NADH and FADH

• GTP and CO2

• 2

• 4

• 6

• 0

How many steps are there in a Citric Acid Cycle?

• 6

• 8

• 9

• 10
