The reaction which occurs in thylakoid interior space:

Explanation

Photolysis, also known as photodissociation or photodecomposition, refers to the process in which a substance is broken down or decomposed into smaller parts by absorbing light energy. In photosynthesis, photolysis occurs during the light-dependent reactions that take place in the thylakoid membranes of chloroplasts. Water molecules are photolyzed to release oxygen, electrons, and protons. This process is a crucial step in the generation of oxygen and the production of energy-rich molecules like ATP.
