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

Difficulty Level:


The chemiosmotic coupling hypothesis of oxidative phosphorylation proposes that Adenosine Triphosphate (ATP) is formed because

(1) high energy bonds are formed in mitochondrial proteins

(2) ADP is pumped out of the matrix into the intermembrane space

(3) a proton gradient forms across the inner membrane

(4) there is a change in the permeability of the inner mitochondrial membrane toward Adenosine Diphosphate (ADP)
