Where did the extra ATP molecules come from. : the synthesis of ATP from ADP and phosphate that occurs in a plant using radiant energy absorbed during photosynthesis. The chloroplasts are where the energy of light is captured, electrons are stripped from water, oxygen is liberated, electron transport occurs, NADPH is formed, and ATP is generated. : the synthesis of ATP from ADP and phosphate that occurs in a plant using radiant energy absorbed during photosynthesis. Well in substrate level for circulation, This phosphate group is transferred from a different molecule directly to the ADP. A:Photosystem 1 is involved in cyclic photophosphorylation reaction. The combination of the two components provides sufficient energy for ATP to be made by the multienzyme Complex V of the mitochondrion, more generally known as ATP synthase. 5 Fig. A system so organized is called a light harvesting complex. It refers to the use of light energy from photosynthesis to ultimately provide the energy to convert ADP to ATP. In cyclic photophosphorylation, the electrons get expelled by photosystem I and they return to the system. Obligate anaerobes are a more potent hydrogen producer in comparison with facultative anaerobes. ATP synthase makes ATP from the proton gradient created in this way. In photosynthesis this commonly involves photolysis, or photodissociation, of water and a continuous unidirectional flow of electrons from water to photosystem II.
