Question

I think I have researched the correct answers but I would like to double-check:

Which enzyme of the citric acid cycle is capable of conserving energy in the form of GTP?

• A. citrate synthase
• B. aconitase
• C. succinate dehydrogenase
• D. isocitrate dehydrogenase
• E. succinyl-CoA synthetase

How many NADH molecules are generated from the complete oxidation of one glucose?

A. 5

B. 7

C. 10

D. 16

E. 32

Overall, the membrane-associated electron transport system pumps __ protons across the membrane for every molecule of NADH that is oxidized.

A. 2

B. 5

C. 6

D. 10

E. 12

Answer 1

Answer E) Succinyl co A- synthetase.

Succinyl co~A synthetase synthesises ATP or GTP. Here Succinyl Co~A is converted into succinate.

Answer 32 molecules of ATP

32 moleculee of ATP is synthesised in the complete break down of glucose. The energy is produced in sequential steps.

Answer 33)

One molecules of NADH synthesises 2.5 molecules of ATP.

One molecule of FADH2 synthesises 1.5 molecules of ATP.

In this case, we have not given 2.5. But 2 is closer to it. That's why 2 is the answer.
