Some leukemias can be treated by introducing asparaginase into blood. This enzyme degrades asparagine, which is required for cancer cell growth. The graph below shows vo vs. [S] plots for two different asparaginases. The arrow below the horizontal axis marks the concentration of asparagine in the blood. Select the best enzyme and rationale that explains which will be most effective in removing asparagine in the blood.image016601c63e5.gif
