- Why bother to eat? What are the three primary uses for cellular energy?Etiology? What does that mean? What does the fact that rotenone appears to increase the susceptibility to Parkinson disease indicate about the etiology of Parkinson disease?Efficiency of ATP Production in Muscle: The transformation of glucose to lactate in myocytes releases only about 7% of the free energy released when glucose is completely oxidized to CO2 and H2O. Does this mean that anaerobic glycolysis in muscle is a wasteful use of glucose? Explain.
- kcat = ? an enzyme has an aspartic acid in the active site with a pKa = 4.0 and the kcat for this enzyme is directly proportional to the fraction of this side chain that is ionized. If the kcat at pH = 4.0 is 52.9x103 s-1 what is the kcat for this enzymes at pH 3.5True or False? Electrons after complex III are then sent immediately to complex IV.
