Which statement is wrong for Krebs' cycle?
- AThere are three points in the cycle where NAD
+
is reduced to NADH+H
+ - BThere is one point in the cycle where FAD
+
is reduced to FADH
2
- CDuring conversion of succinyl CoA to succinic acid, a molecule of GTP is synthesised
- DThe cycle starts with condensation of acetyl group (acetyl CoA) with pyruvic acid to yield citric acid

The Krebs cycle starts with the condensation of Acetyl CoA (2C) with Oxaloacetic acid (4C) to form Citric acid (6C). Statement D incorrectly says it condenses with pyruvic acid (which must first be converted to Acetyl CoA via the link reaction).
