Question

Select the correct option:

Enzymes catalyze the biochemical reactions by .......... the activation energy.

• A. lowering
• B. increasing
• C. unaltering
• D. either (a) or (b)

Answer 1

The correct option is A lowering

Enzymes are macromolecular biological catalysts. which accelerates chemical reactions. Catalysts lower the activation energy (energy required to start a reaction.) for reactions. The lower the activation energy for a reaction, the faster the rate.

So, the correct answer is 'lowering'.
