The Krebs cycle occurs in the:

The carbon-compound that enters the Krebs cycle is:

For each turn of the Krebs cycle, how many CO2 is produced?

How many FADH₂ molecules are produced by 1 molecule of glucose?

• 1

• 3

• 2

• 4

How many FADH₂ molecules are produced by 1 turn of the Krebs Cycle?

• 1

• 4

• 5

• 6

Which of the following is not a requirement for the Krebs Cycle?

• water

• pyruvate

• NAD+

• FAD+

 How many CO₂ molecules are produced by the Krebs Cycle for a molecule of glucose?

• 3

• 2

• 1

• 4

After the Krebs Cycle only a small portion of the energy of glucose has been converted to ATP. At this point the majority of usable energy is contained in

• Citrate

• NADH and FADH2

• Acetyl CoA

• Carbon dioxide
