Pheromones are chemicals

The correct match between Item $I$ and Item $II$ is

Item $I$	Item $II$
$A$. Allosteric effect	$P$. Molecule binding to the active site of enzyme
$B$. Competitive inhibitor	$Q$. Molecule crucial for communication in the body
$C$. Receptor	$R$. Molecule binding to a site other than the active site of enzyme
$D$. Poison	$S$. Molecule binding to the enzyme covalently

$CH_2OOCR' \newline | \newline CHOOCR'' \newline | \newline CH_2OOCR'''$ $\xrightarrow[\text{Hydrolysis}]{\text{Enzyme}} CH_2OH \newline | \newline CHOH \newline | \newline CH_2OH + R'COOH + R''COOH + R'''COOH$
The enzyme used in the above reaction is:

$A$ biological catalyst is essentially

By the action of enzymes,the rate of biochemical reaction
