A) \[{{O}_{2}}\] evolved comes from \[C{{O}_{2}}\]
B) ATP is formed
C) ATP is not formed
D) Water is required as medium but it does not take part in photosynthesis
Correct Answer: B
Solution :
The light driven synthesis of ATP is called photophosphorylation. It takes place during light reaction of photosynthesis. The \[{{O}_{2}}\] evolved during photosynthesis comes from photolysis of water during photosystem-II of light reaction. \[4{{H}_{2}}O2{{H}^{+}}+4O{{H}^{-}}\] \[4O{{H}^{-}}\to 2{{H}_{2}}O+{{O}_{2}}+4{{e}^{-}}\] ATP is not formed in the dark reaction of photosynthesis. It uses the ATP synthesized during light reaction.You need to login to perform this action.
