Vedclass · Answer

(A) The correct matches are as follows:$(1)$ Magnesium $(Mg^{2+})$ acts as a cofactor for many enzymes, including those involved in $ATP$ hydrolysis and photosynthesis, thus it is essential for the activation of enzymes $(S)$.$(2)$ Molybdenum $(Mo)$ is a critical component of the enzyme nitrogenase, which is essential for biological nitrogen fixation $(R)$.$(3)$ Calcium $(Ca^{2+})$ plays a vital role in the coagulation of blood (blood clotting) $(P)$.$(4)$ Sulphur $(S)$ is a key component of certain amino acids like cysteine and methionine, which are essential for protein structure $(Q)$.Therefore, the correct matching is $(1-S), (2-R), (3-P), (4-Q)$.

Column $X$	Column $Y$
$(1)$ Magnesium	$(P)$ Blood clotting
$(2)$ Molybdenum	$(Q)$ Constituent of cysteine amino acid
$(3)$ Calcium	$(R)$ Essential for nitrogen fixation
$(4)$ Sulphur	$(S)$ Activation of enzymes

Column-$I$	Column-$II$
$1.$ Mycorrhiza	$a.$ Free-living $N_2$-fixer
$2.$ Nostoc	$b.$ Phosphorus absorption
$3.$ Azospirillum	$c.$ Leguminous plants
$4.$ Rhizobium	$d.$ Autotrophic $N_2$-fixer
