Why are the two twins experiencing such different symptoms? (Select ALL that apply) A. Michael probably has a genetic inborn error in metabolism that Dave does not B. One brother is in much better shape for the run than the other because of training C. Michael’s case is more severe because he relies on glycolysis (by way of lactic acid fermentation) for energy D. Michael’s supplement has almost no odd-numbered fatty acids, so his body is undergoing more protein and amino acid degradation, and producing dangerous levels of ketones E. Dave’s case is milder because the supplement he is taking contains a significant amount of odd-numbered fatty acids, some of which may be used to produce glucose F. The twins exhibit minor variations in metabolic adaptation to dietary changes based on their genetics
