GENERATION OF ATP As ATP (3 phosphates) is generated, a phosphate group is added to ADP (2 phosphates). This  third phosphate is attached by a high-energy bond—one with lots of energy that can be quickly  released as this unstable bond is broken. Phosphorylation is the process of adding a phosphate  group. Organisms do this in 3 ways: 1. Substrate-level phosphorylation —a high-energy phosphate is directly transferred from a  phosphorylated compound (substrate) to ADP.  C - C - C   P + ADP   C - C - C + ATP 2. Oxidative phosphorylation —electrons are transferred from organic compounds to electron  carriers (usually NAD+), passed through a series of electron carriers, and then finally to oxygen  or some other inorganic molecule.  This process always involves a membrane—the plasma membrane of prokaryocytes and the inner  mitochondrial membrane of eukaryocytes.
