Vedclass · Answer

(A) The correct matches are as follows:$(1)$ Muscle contraction requires $Ca^{+2}$ ions for the exposure of active sites on actin filaments $(Q)$.$(2)$ Digestion of food involves various enzymes, and $Cl^{-}$ ions are essential for the activation of salivary amylase $(T)$.$(3)$ Energy exchange in biological systems is primarily mediated by $ATP$, which contains phosphate groups $(PO_4^{-3})$ $(S)$.$(4)$ Carbohydrate synthesis (e.g., in photosynthesis) involves enzymes like RuBisCO which require $Mg^{+2}$ as a cofactor $(P)$.$(5)$ Nitrogen fixation, particularly in the enzyme nitrogenase, requires Molybdenum $(Mo)$ as a cofactor $(R)$.Therefore, the correct sequence is $(1-Q), (2-T), (3-S), (4-P), (5-R)$.

Column $X$	Column $Y$
$(1)$ Muscle contraction	$(P)$ $Mg^{+2}$
$(2)$ Digestion of food	$(Q)$ $Ca^{+2}$

$E$. Manganese	$V$. Required for synthesis of mitotic spindle	$(v)$. Young root tip begin to die

Column $I$	Column $II$
$(a)$ Boron	$(p)$ For $CO_2$ transport
$(b)$ Copper	$(q)$ Essential for nitrogen fixation
$(c)$ Molybdenum	$(r)$ Essential for sugar translocation in plants
$(d)$ Chlorine	$(s)$ Essential for chlorophyll synthesis in plants

Column-$I$	Column-$II$
$(A)$ Found in some amino acids	$(1)$ $Mg$
$(B)$ Required for photolysis of water	$(2)$ $I$
$(C)$ Not important for plants	$(3)$ $S$
$(D)$ Structural component of chlorophyll	$(4)$ $Mn$
