Uplоаd yоur аnswers tо these questions. Drаw out the reaction that releases acetyl-CoA in the cytosol for fatty acid synthesis. Include substrate and product structures and their names. You will also need to give the name of the enzyme that catalyzes this reaction and indicate any necessary cofactors or co-reactants for full credit. (3 pts.) Before acetyl-CoA can be utilized for fatty acid biosynthesis, it is activated by conversion to malonyl-CoA. Give the name of the enzyme that catalyzes this reaction and the name of the required cofactor. (2 pts.) Draw out the arrow-pushing mechanism for the addition of CO2 to propionyl CoA. (5 pts.) The first round of fatty acid biosynthesis requires two building blocks or reactants attached to fatty acid synthase at the priming and the ACP sites, one of which is the “activated” acetyl-CoA compound. Beginning with these two building blocks, draw out the mechanistic steps (arrow-pushing) involved in the synthesis of acetoacetate (4C) attached to the ACP. (4 pts.) Fatty acid biosynthesis requires a reducing agent. What is the principal reducing agent for fatty acid biosynthesis, and what is the name of the principal pathway that produces this reducing agent? (2 pts.) Reducing agent: Pathway (this was in the homework):
