Which statement is wrong for Krebs' cycle ?

A

There are three points in the cycle where `NAD^(+)` is reduced to `NADH + H^(+)`

B

There is one point in the cycle where `FAD^(+)` is reduced to `FADH_(2)`

C

During conversion of succinyl Co-A to succinic acid, a molecules of GTP is synthesised

D

The cycle starts with condensation of acetyl group (acetyl Co-A) with pyruvic acid to yield citric acid

Text Solution

Verified by Experts

The correct Answer is:
D

Option (d) is incorrect, which can be corrected as Krebs' cycle starts with the condensation of acetyl group with oxaloacetic acid and water to yield citric acid.
During conversion of succinic acid to fumaric acid `FAD^(+)` is reduced to `FADH_(2)` . During conversion of pyruvic acid to acetyl Co-A , isocitrate to oxalosuccine acid and `alpha`-ketoglutaric acid to succinyl Co-A `NAD^(+)` is reduced to `NADPH+H^(+)` .
