Answer:
The correct answer will be 10 conversions.
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.
