Cyclic photophosphorylation results in the formation of
A
ATP
B
NADPH
C
ATP and NADPH
D
ATP, NADPH and $O_2$
Detailed Solution
In cyclic photophosphorylation only PS I is functional; it occurs in the stroma lamellae, which lack PS II and NADP reductase.
The electron excited from P700 is not passed to $NADP^+$; it is cycled back to the PS I complex through the electron transport chain.
This cyclic flow results only in the synthesis of ATP.
NADPH + $H^+$ is not formed, and since PS II is not involved there is no splitting of water and no release of oxygen.
Hence cyclic photophosphorylation results in the formation of ATP only.
