$12$

Vedclass · Answer

(B) The Calvin cycle involves the fixation of $CO_2$ to produce glucose. To synthesize one molecule of glucose $(C_6H_{12}O_6)$,$6$ molecules of $CO_2$ must be fixed. For every molecule of $CO_2$ fixed,$2$ molecules of $NADPH$ and $3$ molecules of $ATP$ are consumed during the reduction and regeneration phases. Therefore,for $6$ molecules of $CO_2$,the total requirement is $6 	imes 2 = 12$ molecules of $NADPH$ and $6 	imes 3 = 18$ molecules of $ATP$.
