Vedclass · Answer

(B) Activation energy is the minimum amount of energy required for a chemical reaction to proceed. Living systems cannot provide high levels of activation energy for most biochemical reactions.Enzymes function as biological catalysts that lower the activation energy barrier,allowing reactions to occur at physiological temperatures.Substrate specificity is a fundamental property of enzymes,meaning a particular enzyme acts only on a specific substrate.While both statements are scientifically correct,the fact that an enzyme is specific to a substrate does not explain *how* or *why* it lowers the activation energy. Therefore,the Reason is not the correct explanation for the Assertion.

$i$. Purely proteinaceous enzyme	$a$. Glucokinase
$ii$. Conjugated enzyme	$b$. Epimerase
$iii$. Transferase enzyme	$c$. Protease
$iv$. Isomerase enzyme	$d$. $FMN$

Assertion : Enzymes lower the activation energy.
Reason : $A$ substrate molecule can be acted upon by a particular enzyme.
