$7.(8$ points total$).$ Below is a simplified diagram of the pyruvate dehydrogenase complex $($PDH complex$)$ with certain molecules and cofactors missing. Using your knowledge of the PDH complex, identify the missing cofactors and molecules in each step of the reaction $($a to $g,4$ points$)$ and explain the role of each enzyme $(E1,E2,$ and E$3)$ in the process, include details about the transfer of functional groups and electron carriers $(3$ points$).$ Mention the general mechanism by which this complex is regulated $(1$ point$).$
