At the same time intracellular polyphosphate is degraded to form ATP, releasing phosphate into the media.

With that enzyme, bacteria can also form ATP if the reaction is running backwards.

The proton gradient across the thylakoid membrane creates a proton-motive force, used by ATP synthase to form ATP.

These redox reactions release energy, which is used to form ATP.

The ADP is then recharged by adding another phosphate to form ATP.

Glucose gets converted to Glucose-6-Phosphate (G6P) through Glucokinase; and G6P is subsequently oxidized to form ATP.

In most cases, the released energies are used to form ATP.

ADP and a phosphate group are combined to form ATP.

Phosphocreatine can anaerobically donate a phosphate group to ADP to form ATP during the first 2 to 7 seconds following an intense muscular or neuronal effort.

Magnesium is a cofactor in more than 300 enzyme-regulated reactions, most importantly reactions forming and using ATP.
