Question

An enzyme accelerates a biochemical reaction by

• A. Increasing substrate movements
• B. Changing free enzyme
• C. Production of heat
• D. Lowering energy of activation

Answer 1

Answer: (D)

Lowering energy of activation

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.
