Question

How many energy conversions occur when both acetyl-CoA molecules go through the krebs cycle?

Answer 1

the answer should be 5 have a very nice day

Answer 2

The correct answer will be 10 conversions.

Step-by-step explanation:

Krebs cycle is a cyclic process of cellular respiration which converts the Actyl-CoA molecules to CO₂ and energy in the form of ATP with some energy stored in the NADH₂ and FADH₂. It provides electrons and protons required for the electron transport chain or ETC.

Krebs cycle starts with the conversion of acetyl-CoA where energy conversion takes place in the step as follows:

1. Iso-citrate to α-ketoglutarate - form NADH₂

2. α-ketoglutarate to succinyl CoA- form NADH₂

3. Succinyl CoA to succinate- form GTP

4. Succinate to fumarate- form FADH₂

5. Malate to oxaloacetate- form NADH₂

1 cycle produces 1 FADH₂, 3 FADH₂ and 1 GTP = 5 conversions

Since cycle completes after two cycles ,therefore, 5X2=10 conversions.

Thus, 10 conversions are the correct answer.
