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 $Y$
