Upload your answers to these questions. In gluconeogenesis, oxaloacetate can be converted in a single step in the matrix of the mitochondria to an intermediate, which is not the final, but the penultimate (next to last) compound in glycolysis. Show this reaction. Draw the structure and name(s) of the product(s) of this reaction and give the name(s) or acceptable abbreviation(s) of any necessary cofactor(s) or co-reactants for the reaction, as well as the name of the enzyme that catalyzes this reaction. (3 pts.) When cytosolic NADH is insufficient to run the GAP dehydrogenase reaction in reverse, oxaloacetate can also be converted to the same penultimate glycolysis intermediate in the cytosol instead of in the matrix. Outline the set of reactions in this case, beginning with oxaloacetate in the mitochondrial matrix and ending with the formation of the penultimate glycolysis intermediate in the cytosol. Structures or names or acceptable abbreviations of compounds and cofactors are sufficient, but all substrates and cofactors must have either a structure or name given. (4 pts.) Oxaloacetate connects to fatty acid biosynthesis via the reaction that forms the shuttle compound responsible for transferring fatty acid building blocks from the mitochondrial matrix to the cytosol. Draw out the reaction that synthesizes this shuttle compound. Draw the structure and name of the product(s) of the reaction and give the name(s) or acceptable abbreviation(s) of any necessary cofactor(s) or co-reactants for the reaction. (3 pts.)
