Question

All of the following involve reduction of coenzymes except:
A. Succinate to Fumarate
B. Isocitrate to a-ketoglutarate
C. Pyruvate to acetyl Co-A
D. Fumarate to Malate

Answer 1

Answer:

isocitrate to a ketoglutarate

Answer 2

Only b is correct answer of this question

Explanation:

• All reactions show reduction of coenzyme except one option that is when Isocitrate convert into ∝ Ketoglutarate
• Oxidation reaction is reaction of gaining of electrons and reduction is gaining of electrons

• Isocitrate to ∝ Ketoglutarate is an oxidative- decarboxylation reaction through enzyme isocitrate-dehydrogenase.

• Succinate to Fumarate convert by using an enzyme succinate dehydrogenase.

• Fumarase is enzyme for converting the fumarate to malate.
• Option b is correct answer.
