# AP Biology - Starch

Hello, I'm in deep need of your knowledge. If you may help me, I would appreciate it. The question is regarding the high catalyzation of starch, since it breaksdown at 100 C, why is the high temperature needed?

Thanks
-Sally

As I remember, the action of the enzyme polyphenol oxidase depends on temperature. You may want to look that enzyme up.
