Question

Enzymes ____________. A) are highly specific protein catalysts B) decrease the number of chemical reactions C) increase the activation energy required for chemical reactions D) undergo changes when participating in chemical reactions

Answer 1

Answer:

A) Enzymes are highly specific protein catalysts

Explanation:

1. Enzymes are highly specific protein catalysts i.e. it react with only that substrate for which it has been made.
2. Enzymes have an active site by which it binds to substrate at that specific site.
3. Enzymes lowers the activation energy required for completion of a chemical reaction. As a result rate of the reaction increases.
4. Enzymes never participate in a chemical reaction rather they are obtained back in its original form on the completion of the reaction.
