A) This process takes place in the stromal lamellae
B) ATP synthesis takes place
C) \[NADPH+{{H}^{+}}\]is synthesized
D) Takes place only when light of wavelength beyond 680 nm is available for excitation
Correct Answer: C
Solution :
Cyclic flow of light reaction is the process, of photosynthesis in which light of wavelength more than 680 nm is required. It takes place in the stromal lamella of the chloroplast. During cyclic photophosphorylation only the synthesis of ATP takes place (i.e. not \[NADPH+{{H}^{+}}\]) because the stroma lamellae do not possess enzyme NADP reductase due to which the excited electrons in the cyclic flow do not pass on to NADP instead get back to the PS-I complex only.
