Vedclass · Answer

(B) The Assertion is correct because the Calvin cycle requires $6$ molecules of $CO_2$,$12$ molecules of $NADPH + H^+$,and $18$ molecules of $ATP$ to synthesize one molecule of hexose (glucose).The Reason is also correct because the light-dependent reaction (photophosphorylation) produces $ATP$ and $NADPH + H^+$ (often written as $NADPH_2$) which are then utilized in the dark reaction (Calvin cycle).However,the Reason does not directly explain why exactly $6$ $CO_2$,$12$ $NADPH$,and $18$ $ATP$ are required; it only states the source of these molecules. Therefore,the Reason is not the correct explanation of the Assertion.

Assertion: Six molecules of $CO_2$ and twelve molecules of $NADPH + H^+$ and $18\, ATP$ are used to form one hexose molecule.
Reason: Light reaction results in the formation of $ATP$ and $NADPH_2$.
