Vedclass · Answer

(D) Statement $S$ is false because the major anion in human blood is bicarbonate $(HCO_3^-)$ or chloride $(Cl^-)$ is present,but it is not the 'major' anion in the context of physiological buffering systems where bicarbonate dominates.However,in the context of biological mineral nutrition,Chlorine is primarily an essential micronutrient for plants involved in water splitting during photosynthesis.Statement $R$ is true because Molybdenum is a crucial component of the enzyme nitrogenase,which is essential for biological nitrogen fixation in plants.Therefore,$S$ is false and $R$ is true.

Column $I$	Column $II$
$(A)$ Chlorine	$(i)$ Important for $ATP$ and carbohydrate synthesis
$(B)$ Calcium	$(ii)$ Synthesis of hemoglobin and chlorophyll
$(C)$ Magnesium	$(iii)$ Essential for nucleic acid synthesis
$(D)$ Zinc	$(iv)$ Required for muscle contraction
$(E)$ Copper	$(v)$ Plays an important role in $CO_2$ transport
	$(vi)$ Required for the splitting of water

$S$ - Statement: Chlorine is the major anion present in the blood.
$R$ - Reason: Molybdenum is required for nitrogen fixation in plants.
