Question

Enzyme function is to

• A. Change equilibrium
• B. Cause biochemical reaction
• C. Change the direction of reaction
• D. Change the rate of biochemical reaction

Answer 1

Answer: (D)

Change the rate of biochemical reaction

Enzymes are proteins which accelerate the rate of the reaction. The substrate and product have different energy state. The energy gap between the substrate and the product is known as activation energy which is the minimum energy required to initiate a reaction. The enzymes lower the activation energy and lead to the faster conversion of substrate to the product.

So, the correct answer is option D.
