Question

Which statement is wrong for Krebs' cycle ?
(1) There is one point in the cycle where FAD+ is reduced to FADH₂
(2) During conversion of succinyl CoA to succinic acid, a molecule of GTP is synthesised
(3) The cycle starts with condensation of acetyl group (acetyl CoA) with pyruvic acid to yield citric acid.

(4) There are three points in the cycle where NAD⁺ is reduced to NADH + H⁺

Answer 1

The correct answer is (3)

Krebs cycle begins with condensation of acetyl CoA (2C) with oxaloacetic acid (4C) to form citric acid (6C).
