Which statement is wrong for Krebs' cycle?
There is one point in the cycle where FAD+ is reduced to FADH2.
During conversion of succinyl CoA to succinic acid, a molecule of GTP is synthesized.
The cycle starts with condensation of acetyl group (acetyl CoA) with pyruvic acid to yield citric acid.
There are three points in the cycle where NAD+ is reduced to NADH + H+.
the Tricarboxylic Acid (TCA) cycle (Krebs' cycle) begins with the condensation of an acetyl group (from Acetyl CoA) with oxaloacetic acid (OAA) and water to yield citric acid . Statement 3 is incorrect because it identifies pyruvic acid as the condensation partner; pyruvic acid is actually the substrate that is converted into Acetyl CoA before entering the cycle . All other statements are facts supported by the text: there are three points where NAD+ is reduced, one point where FAD+ is reduced, and GTP is synthesized during the conversion of succinyl-CoA to succinic acid .
