Which of the following statements is true with regard to the light reaction of photosynthesis?

(A)In PS-II, the reaction centre chlorophyll-a has an absorption peak at 700 nm, hence is called P700
(B)In PS-I, the reaction centre chlorophyll-a has an absorption maximum at 680 nm and is called P680
(C)The splitting of the water molecule is associated with PS-I
(D)Photosystem-I and II are both involved in the Z-schemeCorrect

Answer: (D)

Solution

PS-II's reaction centre is P680 and PS-I's is P700 (so (a) and (b) are reversed), and photolysis of water is linked to PS-II, not
