Question

An enzyme brings about
(a) decrease in reaction time
(b) increase in reaction time
(c) increase in activation energy
(d) reduction in activation energy

Answer 1

Answer:

Enzyme is a biological catalyst , and they decreases the activation energy

Answer 2

An enzyme brings about reduction in activation energy. (Option D)

• We know that enzymes are biochemical substances which decreases the time of different biochemical reactions.

• For this,they actually deceases the necessary amount of energy for the biochemical reaction which is also known as the activation energy.

• To specifically describe the work of an enzyme we can say that it decreases the reaction activation energy instead of just saying that enzymes increases the speed of the reaction.
