Enzymes with two sites are called

Which site of an enzyme is called an allosteric site?

Statements about Enzyme Inhibitor Drugs are given below.
$A$. There are Competitive and Non-competitive inhibitor drugs.
$B$. These can bind at the active sites and allosteric sites.
$C$. Competitive Drugs are allosteric site blocking drugs.
$D$. Non-competitive Drugs are active site blocking drugs.
Choose the correct answer from the options given below.

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:

Identify the correct pair having amino acid $(A)$ and the hormone $(B)$ that is an iodinated derivative of the amino acid $(A)$. ($T$ and $Y$ represent one-letter codes for amino acids.)

Enzyme activity is maximum at $.......$ $K$.
