Detailed explanation-1: -When the cell has extra energy (gained from breaking down food that has been consumed or, in the case of plants, made via photosynthesis), it stores that energy by reattaching a free phosphate molecule to ADP, turning it back into ATP.
Detailed explanation-2: -As the electrons are passed through the chain hydrogen ions are pumped into the intermembrane space. This creates a hydrogen ion gradient, a source of stored energy. The enzyme ATP synthase can use the energy stored in this gradient to add a phosphate group to ADP to create ATP for the cell.
Detailed explanation-3: -Photophosphorylation is a method specific to plants and cyanobacteria. It is the creation of ATP from ADP using energy from sunlight, and occurs during photosynthesis. ATP is also formed from the process of cellular respiration in the mitochondria of a cell.
