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	$(Q)$ $Ca^{+2}$
$(3)$ Energy exchange	$(R)$ $Mo$
$(4)$ Carbohydrate synthesis	$(S)$ $PO_4^{-3}$
$(5)$ Nitrogen fixation	$(T)$ $Cl^{-}$

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	$(4)$ $Mn$

Column-$I$	Column-$II$
$(A)$ Water splitting reaction	$(1)$ Boron
$(B)$ Uptake and utilisation of $Ca^{2+}$	$(2)$ Copper
$(C)$ Synthesis of auxin	$(3)$ Chlorine
$(D)$ Redox reaction	$(4)$ Zinc
