Photosynthesis in Higher PlantsMedium
Question
Photochemical reactions in the chloroplast are directly invovled in
Options
A.formation of phosphoglyceric acid
B.fixation of carbon dioxide
C.synthesis of glucose and starch
D.photolysis of water and phosphorylation of ADP to ATP
Solution
CO2 is fixed in the stroma of the chloroplast leadimg to the synthesis of PGA from which glyceraldehyde phosphate is formed. From glyceraldehyde phosphate, sugar and starch are formed. All these do not require light. However, photolysis of water and phosphorylation of ADP to ATP requires light energy.
