Which of the following substances is responsible for controlling the sugar level in the blood?

Match the following enzymes given in Column-$I$ with the reactions they catalyse given in Column-$II$.

Column-$I$ (Enzymes)	Column-$II$ (Reactions)
$A$. Invertase	$1$. Decomposition of urea into $NH_3$ and $CO_2$
$B$. Maltase	$2$. Conversion of glucose into ethyl alcohol
$C$. Pepsin	$3$. Hydrolysis of maltose into glucose
$D$. Urease	$4$. Hydrolysis of cane sugar
$E$. Zymase	$5$. Hydrolysis of proteins into peptides

What is the function of enzymes in biological systems?

How do enzymes catalyse a chemical reaction in the living system? Explain drug-target interaction taking the example of an enzyme as a target.

Insulin and glucagon,which are responsible for maintaining the blood glucose level,fall under:

Match List-$I$ with List-$II$:

List-$I$ (Reaction)	List-$II$ (Enzyme)
$A$. Hydrolysis of starch to maltose	$I$. Diastase
$B$. Conversion of proteins to peptides	$II$. Pepsin
$C$. Hydrolysis of sucrose to glucose and fructose	$III$. Invertase
$D$. Glucose to ethanol	$IV$. Zymase

The correct answer is:
