Question

Read the following four statements A, B, C and D and select the right option having both correct statements:
(A) Z-scheme of light reaction takes place in the presence of PSI only
(B) Only PSI functional in cyclic photophosphorylation
(C) Cyclic photophosphorylation results in a synthesis of ATP and NADPH2
(D) Stroma lamellae lack PSII as well as NADP

Accepted Answer

According to the NCERT text: 
1. Statement A is incorrect: The Z-scheme of light reaction involves both PS II and PS I working in a series .
2. Statement B is correct: When only PS I is functional, the electron is circulated within the photosystem and phosphorylation occurs due to cyclic flow .
3. Statement C is incorrect: Cyclic photophosphorylation results only in the synthesis of ATP, but not of NADPH + H+ .
4. Statement D is correct: The stroma lamellae membranes lack PS II as well as the NADP reductase enzyme .
