Answer:

Correct Answer: B

Solution:

Activation energy is an external supply of energy which is needed for the initiation of the chemical reaction.

Activation energy required for such a large number of reactions cannot be provided by living systems.

Enzymes lower the activation energy required for a reaction.

Enzymes are generally specific for their substrates.
