The $ATP$ can be made by photophosphorylation, oxidative phosphorylation, and substrate-level phosphorylation. In photophosphorylation, $ATP$ is made by $ADP$ in the presence of light. In substrate-level phosphorylation, phosphoryl group transfers to $ADP,$ which results in the formation of $ATP.$ In oxidative phosphorylation, when electrons are transferred from $NADH$ or $FADH$ $_{2}$ to $O _{2}$, its results in the formation of $ATP.$
