Which of the following statement related to Kreb's cycle is not correct?
Options
- AThere is only one reaction in Kreb's cycle where FAD + is reduced to F A D H 2
- BDuring conversion of succinyl CoA to succinic acid, a molecule of GTP is synthesized.
- CThe cycle starts with reaction of acetyl CoA with pyruvic acid to form 6C citric acid.
- DThere are three reactions in the cycle where N A D + is reduced to N A D H + H + .
Correct answer
C. The cycle starts with reaction of acetyl CoA with pyruvic acid to form 6C citric acid.
Step-by-step solution
Kreb's cycle also known as citric acid cycle in which first reactant oxalo acetic acid (4C) reacts with Acetyl CoA (2C) to form first stable compound citric acid which is 6 carbon compound. Total 4 dehydrogenation reaction occurs in Kreb's cycle in which N A D + is hydrogen acceptor in 3 reaction and F A D + is hydrogen acceptor in one reaction.
