Solution
The correct option is A Both Assertion and Reason are correct and Reason is the correct explanation for Assertion
The chemical or metabolic conversion refers to a reaction. Most of the chemical reactions do not start automatically because the reactant molecules have an energy barrier to become reactive. Therefore, an external supply of energy is needed for the start of the chemical reaction. It is called activation energy. Enzymes lower the activation energy required for a reaction.
So, the correct answer is 'Both Assertion and Reason are correct and Reason is the correct explanation for Assertion'.
