Your friend recently had some tests reveal that a mutation caused the hexokinase enzymes in her muscle cells to now have a higher Km in the presence of glucose. Using the graph below: Which line represents hexokinase’s previous affinity for glucose? Which star represents hexokinase’s previous Km? How would hexokinase have reacted to low and high amounts of glucose in this state? Which line represents hexokinase’s mutated affinity for glucose? Which star represents hexokinase’s mutated Km? How would hexokinase now react to low and high amounts of glucose with this mutation? Would this change be good or bad?
