These ATP generating mechanisms proceed by one or both of two mechanisms in living organisms: Oxidative phosphorylation: oxygen-dependent, converts the chemical energy of fuel substances into energy bound into ATP Substrate-level phosphorylation: serves as the primary source of ATP for cells living temporarily or permanently without oxygen Overview of Pathways Producing ATP Oxidative phosphorylation can be divided into three overall parts which are common to all living organisms possessing this pathway: A series of reactions that provide a source of electrons at elevated energy levels.
