Show Answer
Answer : a
Hints & Solution
(a) Photolysis is catalysed by the proteinbound inorganic complex containing manganese ions (oxygen evolving complex) of photosystem II. Photolysis is the process by which water is split into oxygen, which is released into the atmosphere, and hydrogen. The hydrogen then becomes bonded to the coenzyme NADP to form NADPH and is transferred to the Calvin Cycle along with ATP.
