1. The breakdown of fatty acids can generate a large amount of Acetyl-CoA. In light of this and of the factors that regulate the TCA cycle, what would be the effect of fatty acid breakdown on pyruvate dehydrogenase AND on glycolysis and why is this effect advantageous to the cell when fatty acids are being broken down? Fatty acid breakdown 2. For the following statement, decide whether the statement is true or false and provide a justification for your answer:...
