The phosphorylation of ADP to form ATP is an _____ reaction that _____ energy. In the process of photosynthesis the phosphorylation of ADP to form ATP using the energy of sunlight is called photophosphorylation. Cyclic photophosphorylation occurs in both aerobic and anaerobic conditions. Only two sources of energy are available to living organisms: sunlight and reduction-oxidation (redox) reactions. All organisms produce ATP which is the universal energy currency of life. In photosynthesis this commonly involves photolysis or photodissociation of water and a continuous unidi… In the process of photosynthesis the phosphorylation of ADP to form ATP using the energy of sunlight is called photophosphorylation.

In photosynthesis this commonly involves photolysis or photodissociation of water and a continuous unidi… Oxidative phosphorylation is the metabolic pathway in which cells use enzymes to oxidize nutrients thereby releasing the chemical energy stored within in order to produce adenosine triphosphate (ATP). In most eukaryotes this takes place inside mitochondria. Almost all aerobic organisms carry out oxidative phosphorylation. This pathway is so pervasive because it releases more energy than alternative fermentation processes such as anaerobic glycolysis. Free ADP is transported from the cytoplasm to the mitochondrial matrix while ATP produced from oxidative phosphorylation is transported from the mitochondrial matrix … Photophosphorylation - Wik...
