Question
Photochemical reactions in the chloroplasts are directly involved in
- (a) Fixation of carbon dioxide
- (b) Synthesis of glucose and starch
- (c) Formation of phosphoglyceric acid
- (d) Photolysis of water and phosphorylation of ATP to ATP
The correct answer is: (d) Photolysis of water and phosphorylation of ATP to ATP
Photochemical reaction is also known as light reaction because it takes place in the presence of light in the grana portion of chloroplast. In this reaction, photolysis of water takes place, which generates oxygen, simultaneously,photophosphorylation takes place which generates ATP and NADPH.
