Solution

ATP stores energy from catabolic reactions & releases it later to drive anabolic reactions.

ATP is generated when a high energy P is transferrred from a phosphorylated compound to ADP (Ex: PEP to Pyruvic Acid)
Oxidative phosphorylation: Electrons are passed from organic compounds to electron carriers (NAD+) and brought to ETC to generate ATP
Photophosphorylation: the phosphorylation of ADP to form ATP using the energy of sunlight.
