DENDROLOGY

Detailed explanation-1: -Splitting of H2O molecules into hydrogen ions and oxygen in the presence of light and grana is photolysis. The photolysis reaction is carried out by the photosystem II which is present in the membrane of thylakoids. A photosystem is made up of chlorophyll molecules and some other proteins.

Detailed explanation-2: -The chlorophyll’s donated electrons need to be replaced, and these electrons come from the splitting of water. In a process called photolysis (’light’ and ‘split’), light energy and catalyst s interact to drive the splitting of water molecules into protons (H+), electrons, and oxygen gas.

Detailed explanation-3: -In this process of photolysis (“splitting by light”), H2O molecules are broken into hydrogen ions, electrons, and oxygen atoms.

Detailed explanation-4: -Electrolysis is the process of using electricity to split water into hydrogen and oxygen. This reaction takes place in a unit called an electrolyzer.

Detailed explanation-5: -The mechanism of photosynthetic water splitting† Water splitting is catalyzed by the oxygen-evolving complex (OEC) of PSII, producing dioxygen gas, protons and electrons.
