Question

Which statement is wrong for Krebs cycle?

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

Answer 1

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

Krebs cycle starts with condensation of acetyl group (acetyl CoA) with oxaloacetate to form a tricarboxylic, 6-carbon compound called citric acid.
