Detailed explanation-1: -Photophosphorylation is a process that occurs during photosynthesis in which a phosphate group is added to ADP to form ATP. Energy from light is used to run the reaction.
Detailed explanation-2: -ATP is also synthesized by the light-dependent reactions, via chemiosmosis.
Detailed explanation-3: -The Calvin cycle takes place in the stroma and uses the ATP and NADPH from the light-dependent reactions to fix carbon dioxide, producing three-carbon sugars-glyceraldehyde-3-phosphate, or G3P, molecules. The Calvin cycle converts ATP to ADP and Pi, and it converts NADPH to NADP+.
Detailed explanation-4: -Yes, oxygen is produced in the light reaction of photosynthesis in lumen thylakoid by the photolysis of water.
Detailed explanation-5: -The Two Parts of Photosynthesis In the light-dependent reactions, which take place at the thylakoid membrane, chlorophyll absorbs energy from sunlight and then converts it into chemical energy with the use of water. The light-dependent reactions release oxygen from the hydrolysis of water as a byproduct.
