Detailed explanation-1: -Cyclic photophosphorylation produces ATP only. It does not involve the formation of NADPH .
Detailed explanation-2: -Photophosphorylation does not require carbon dioxide. During photophosphorylation energy from light is used to generate ATP. Absorption of light is mediated by a protein complex called photosystem (PS).
Detailed explanation-3: -Both ATP and NADPH molecules get formed. Water is not needed in the cyclic photophosphorylation process. Water is needed in the process and the process of photolysis takes place as well. NADPH does not get produced.
Detailed explanation-4: -In cyclic photophosphorylation PS-I is involved and the excited electron follows a cyclic pathway. ATP is produced during this process.
Detailed explanation-5: -Cyclic Photophosphorylation. Cyclic Photophosphorylation happens with the help of photosynthesis, a process of producing carbohydrates by green plants using carbon dioxide and water in the presence of sunlight.
