Photophosphorylation is the conversion of ADP to ATP using the energy of sunlight by activation of PSII. Indeed, it is believed that essentially all of the oxygen in the atmosphere today is the result the splitting of water in photosynthesis over the many eons that the process has existed. It is the process of synthesizing energy-rich ATP molecules by transferring the phosphate group into ADP molecule in the presence of light. This process is similar to oxidative phosphorylation in several ways.

This system, called cyclic photophosphorylation (Figure \(\PageIndex{8}\)) which generates more ATP and no NADPH, is similar to a system found in green sulfur bacteria. In mechanism, photophosphorylation is most similar to(A) substrate-level phosphorylation in glycolysis. On the other hand, in non-cyclic photophosphorylation, the electrons that are expelled by the photosystems do not return. Respiration is the process in which the cells of an organism obtain energy by, Q:What is ADP C. carbon fixation. How does A differ? The electron transport complexes of photosynthesis are also located on the thylakoid membranes. 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. Expert Help. Oxygen is used to construct the basic building blocks of life, such as carbohydrates, lipids, and nucleic acids.
