Assertion and Reason both are correct but Reason is not the correct explanation of Assertion.

Vedclass · Answer

(B) $1$. In the $C_3$ cycle (Calvin cycle),the fixation of one molecule of $CO_2$ requires $3$ $ATP$ and $2$ $NADPH$ molecules.$2$. The light reaction produces $ATP$ and $NADPH$ in a specific ratio. However,the $C_3$ cycle requires a higher ratio of $ATP$ to $NADPH$ than what is produced by non-cyclic photophosphorylation alone.$3$. Cyclic photophosphorylation occurs to produce additional $ATP$ to compensate for this deficit.$4$. While both statements are scientifically accurate,the Reason does not directly explain why the $C_3$ cycle specifically requires $3$ $ATP$ and $2$ $NADPH$; it only explains how the cell manages the $ATP$ demand. Therefore,the Reason is not the correct explanation for the Assertion.

$A$: For every $CO_2$ molecule entering the $C_3$ cycle,three molecules of $ATP$ and two molecules of $NADPH$ are required.
$R$: Cyclic photophosphorylation takes place to meet the difference in the number of $ATP$ molecules.
