2. Draw the reactions catabolizing the amino acid valine into isobutryl-CoA, specifically one transamination reaction (for which you do not need to show the mechanism) and one dehydrogenation reaction (which is analogous to the pyruvate dehydrogenase reaction mechanism, and for which you need to show the mechanism using arrow pushing and including the relevant cofactors).
