What is effect of temperature?Show answer
As temperature rises, molecules move faster and collide more often, so enzyme activity increases up to an optimum. Beyond the optimum, the heat breaks the bonds holding the enzyme's shape, and the active site changes so the substrate no longer fits. This is denaturation, and it is usually permanent. Human enzymes typically work best near body temperature.
What are inhibitors?Show answer
Inhibitors are molecules that reduce enzyme activity:
