Which statement is wrong for krebs’ cycle?

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 is ${\rm{NA}}{{\rm{D}}^{\rm{ + }}}$ is reduced to ${\rm{NADH}}\,{\rm{ + }}\,{{\rm{H}}^{\rm{ + }}}$

There is one point in the cycle where ${\rm{FA}}{{\rm{D}}^ + }$ is reduced to ${\rm{FAD}}{{\rm{H}}_2}$

During conversion of succinyl CoA to succinic acid, a molecule of GTP is synthesised
