Your cousin tells you about this amazing new dietary supplement he found on the internet that boosts energy and increases endurance. You look up the main ingredient and learn that this chemical is a form of pyruvic acid.   This form has been found to be able to cross the double membrane and enter the mitochondria. You have just learned about cellular respiration in your biology class, so give your cousin a detailed explanation of the likely effect of these pills on the metabolic pathways in his cells. What process in cellular respiration is likely to be affected, how does it normally function and what will change as a result of taking these supplements?  Is it likely to increase energy and endurance? Why or why not? For full credit, be sure to discuss enzymes, membranes, and ATP.
