Question

Which statement is wrong for Kreb's cycle?

• A. There is one point in the cycle where $FA{D}^{+}$ is reduced to $FAD{H}_2$
• B. During conversion of succinyl coA to succinic acid, a molecule of GTP is synthesised
• C. The cycle starts with condensation of acetyl group (acetyl CoA) with pyruvic acid to yield citric acid
• D. There are three points in the cycle where $NA{D}^{+}$ is reduced to $NADH+H^{+}$

Answer 1

The correct option is C The cycle starts with condensation of acetyl group (acetyl CoA) with pyruvic acid to yield citric acid

Kerb's cycle also known as citric acid cycle

It begins with condensation of an acetyl group (acetyl CoA (2C)) with oxaloacetic acid (or pyruvic acid) (4C) to form citric acid (6C) with the addition of water molecule (hydration).

Hence the correct answer is the option 'The cycle starts with condensation of an acetyl group (acetyl CoA) with pyruvic acid to yield citric acid'.
