The following video shows how the rate of the potato catalase depends on the pH. Do you have a hypothesis why both low and high pH slow down the enzyme compared to neutral pH? Which acid/base groups are part of the mechanism described above? | The following video shows how the rate of the potato catalase depends on the pH. Do you have a hypothesis why both low and high pH slow down the enzyme compared to neutral pH? Which acid/base groups are part of the mechanism described above? How is the structure (shape) of the enzyme affected by changes in pH? | ||
