Which one of the following is a conjugate protein?

Select the correct option for the following matches:

List-$I$	List-$II$
$(1)$ Non-polar $R$ group	$(a)$ Tyrosine
$(2)$ Polar positive $R$ group	$(b)$ Glutamic acid
$(3)$ Polar negative $R$ group	$(c)$ Histidine
$(4)$ Polar uncharged $R$ group	$(d)$ Tryptophan

Assertion: Human diet should compulsorily contain glycine,serine,and tyrosine.
Reason: Essential amino acids cannot be synthesized in the human body.

Match the following columns:

Column-$I$ (Protein)	Column-$II$ (Function)
$P$. Collagen	$I$. Hormone
$Q$. Trypsin	$II$. Sensory receptor
$R$. Insulin	$III$. Fights infectious agents
$S$. Antibody	$IV$. Enzyme
$T$. Receptor	$V$. Intercellular ground substance
$U$. $GLUT-4$	$VI$. Enables glucose transport into cells
