(B) In the $TCA$ cycle (also known as the Krebs cycle),one molecule of Acetyl $CoA$ undergoes a series of reactions to produce the following energy-rich molecules:$1$. $3$ molecules of $NADH$ are produced,which yield $3 	imes 3 = 9$ $ATP$ molecules via oxidative phosphorylation.$2$. $1$ molecule of $FADH_2$ is produced,which yields $2$ $ATP$ molecules via oxidative phosphorylation.$3$. $1$ molecule of $GTP$ (or $ATP$) is produced directly via substrate-level phosphorylation,which is equivalent to $1$ $ATP$.Adding these together,the total $ATP$ yield per Acetyl $CoA$ molecule is $9 + 2 + 1 = 12$ $ATP$.

Number of total $ATP$ generated in $TCA$ cycle per Acetyl $CoA$ molecule is
