Q. Cyclic photophosphorylation results only in the

A) Formation of ATP
B) Formation of $NADP^{+} + H^{+}$ and ATP
C) Formation of $NAD^{+} + H^{+}$
D) Formation of ADP + Pi
Explanation

During the cyclic phosphorylation, the electrons does not pass to the $NADP^{+}$ but cycled back to PS-I through electron transport chain. This cyclic flow hence, results only in the synthesis of ATP but no of NADPH + $H^{+}$. Cyclic photophosphorylation occurs when only light of wavelength beyond 700 nm is available for excitation
