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

Correct answer · Option D

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

Krebs cycle starts with the condensation of acetyl group with oxaloacetic acid (OAA) and water to yield citric acid, not pyruvic acid.
