Glycolysis

Match the following columns:

Column-$I$ (Molecules)	Column-$II$ (Number of Carbon and Phosphorus)
$P$. Fructose $1, 6$-bisphosphate	$I$. $(C-3), (P-2)$
$Q$. Glucose-$6$-phosphate	$II$. $(C-3), (P-1)$
$R$. $DHAP$	$III$. $(C-6), (P-2)$
$S$. $BPGA$	$IV$. $(C-6), (P-1)$

Choose the correct option:
$(1)$ Glucose and fructose are phosphorylated by the enzyme transferase/hexokinase to form glucose $6$-phosphate.
$(2)$ In fermentation,yeast converts glucose into ethanol under aerobic/anaerobic conditions.

Select the correct sequence of reactions in glycolysis:
$(a)$ $3$-phosphoglyceraldehyde $\rightarrow$ $1,3$-biphosphoglycerate
$(b)$ $3$-phosphoglyceric acid $\rightarrow$ $2$-phosphoglycerate
$(c)$ $1,3$-biphosphoglyceric acid $\rightarrow$ $3$-phosphoglyceric acid
$(d)$ Splitting of $1,6$-fructose biphosphate to dihydroxyacetone phosphate and $3$-phosphoglyceraldehyde
