Question

Which process in the light-dependent reactions results in the release of hydrogen ions, electrons, and oxygen?

Answer 1

The light dependent spliting of water molecules into protons(hydrogen ions) , electrons and oxygen is called photolysis of water.

Answer 2

Electron Transport Chain is the process in the light-dependent reactions results in the release of hydrogen ions, electrons, and oxygen.

Explanation:

The electron transport chain (ETC) is a progression of reactions in which the electrons moves  from electron givers to electron acceptors by means of redox (both decrease and oxidation happening all the while) responses, and couples this electron move with the exchange of protons (H+ particles) over a layer. The end product of this reaction is hydrogen ions, electrons and oxygen together which leads to the formation of water molecules.
