How does photophosphorylation differ from oxidative phosphorylation?

Photophosphorylation does not involve an electron transport chain, while oxidative phosphorylation does.

Photophosphorylation uses light energy, while oxidative phosphorylation uses chemical energy.

Photophosphorylation occurs in mitochondria, while oxidative phosphorylation occurs in chloroplasts.

Photophosphorylation produces NADH, while oxidative phosphorylation produces NADPH.
