Question

How do enzymes speed up

chemical reactions?
A. Enzymes provide a site where activation
energy is greatly reduced.
B. Enzymes eliminate the need for activation
energy.
C. Enzymes do not speed up chemical reactions.

Answer 1

A

Step-by-step explanation:

One of the biggest things about enzymes is their special lock and key fit. This describes the active site of the enzyme where the substrate (the molecule being reacted on) fits in perfectly. This means the enzyme can make the perfect conditions for that molecule to react in, which decreases the activation energy.
