Which statement is wrong for Krebs' cycle?

1. There are three points in the cycle where NAD+ is reduced to NADH + H+
2. There is one point in the cycle where FAD+ is reduced to FADH2
3. During conversion of succinyl Co-A to succinic acid, a molecule of GTP is synthesised
4. The cycle starts with condensation of acetyl group (acetyl Co-A) with pyruvic acid to yield citric acid
