The link between glycolysis and the Kreb's cycle is:

Match the columns based on the number of carbon atoms in the compounds involved in the Krebs cycle:

Column-$I$	Column-$II$
$(a)$ $4$ $C$ compound	$(1)$ Acetyl $CoA$
$(b)$ $2$ $C$ compound	$(2)$ Pyruvate
$(c)$ $5$ $C$ compound	$(3)$ Citric acid
$(d)$ $3$ $C$ compound	$(4)$ $\alpha$-Ketoglutaric acid
	$(5)$ Malic acid

In the Krebs cycle,the acceptor of acetyl $CoA$ is .........

Match the compounds given in column-$I$ with the number of carbon atoms present in them which are listed under column-$II$. Choose the answer which shows the correct combination of alphabets of the two columns.

Column-$I$	Column-$II$
$A$. Oxaloacetate	$p$. $6-C$ compound
$B$. Phosphoglyceraldehyde	$q$. $5-C$ compound
$C$. Isocitrate	$r$. $4-C$ compound
$D$. $\alpha$-Ketoglutarate	$s$. $3-C$ compound
	$t$. $2-C$ compound
