Question

Arrange the following reactions of citric acid cycle in correct order:
(A) Formation of Alpha-ketoglutarate
(B) Conversion of Alpha-ketoglutarate to succinyl CoA
(C) Formation of citrate
(D) Citrate is isomerized to isocitrate
(E) Formation of succinate
Choose the correct answer from the options given below:

• A. (D), (B), (C), (E), (A)
• B. (C), (B), (D), (A), (E)
• C. (C), (D), (A), (B), (E)
• D. (A), (C), (D), (E), (B)

Hint:

The citric acid cycle is a critical part of cellular respiration where energy is generated through oxidation reactions

Answer 1

The Correct Option is C

The correct order of the citric acid cycle steps is formation of citrate isomerization of citrate to isocitrate formation of alpha-ketoglutarate conversion of alpha-ketoglutarate to succinyl CoA and formation of succinate
