NADP reductase, located on stroma side of membrane, obtains e- from PSI and protons from stroma to form NADPH2 (III). Cytochrome system transport electrons and pumps H+ from stroma to thylakoid space (IV). PSII oxidises water (V).

Q. Following steps in random order are given below for photophosphorylation through chemiosmosis -
(I). $ATP$ synthase produces $ATP$ due to flow of $H^{+}$ from thylakoid lumen to stroma
(II). $NADP$ reductase, located on stroma side of membrane, obtains $e^{-}$ from $PSI$ and protons from stroma to form $NADPH_{2}$
(III). Cytochrome system transport electrons and pumps $H^+$ from stroma to thylakoid space
(IV). $PSII$ oxidises water
(V). Reaction centre of $PSII$ gets photoexcited having released electrons
The correct sequence is -

Photosynthesis in Higher Plants

Solution:

Correct answer is (b) V, IV, III, II, I
