The ADP is converted to (7) ______. This process is called (8) ______. During the dark phase, the compound produced at the end of the light reaction reacts with carbon dioxide to form (9) ______. This product is converted to starch. The process is called (10) ______.
उत्तर
Photosynthesis involves light reaction and dark reaction. During light reaction, the chlorophyll present in the leaves gets activated by absorbing light energy. This energy splits water molecules to hydrogen ion and oxygen and releases two electrons. This process is called photolysis. The hydrogen ions are picked up by NADP to form NADPH2. The ADP is converted to ATP. This process is called photophosphorylation. During the dark phase, the compound produced at the end of the light reaction reacts with carbon dioxide to form glucose. This product is converted to starch. The process is called polymerization.
