Answer:
<h3>A) Enzymes are highly specific protein catalysts</h3>
Explanation:
- Enzymes are highly specific protein catalysts i.e. it react with only that substrate for which it has been made.
- Enzymes have an active site by which it binds to substrate at that specific site.
- Enzymes lowers the activation energy required for completion of a chemical reaction. As a result rate of the reaction increases.
- Enzymes never participate in a chemical reaction rather they are obtained back in its original form on the completion of the reaction.
