Detailed explanation-1: -During this process, the electrons in water are removed and passed to the reaction centre chlorophyll. The associated hydrogen ions are released from the water molecule, and after two water molecules are thus split, the oxygen atoms join to form molecular oxygen (O 2 ), a waste product of photosynthesis.

Detailed explanation-2: -Therefore, approximately one-third of the available light energy is captured as NADPH during photolysis and electron transfer. An equal amount of ATP is generated by the resulting proton gradient. Oxygen as a byproduct is of no further use to the reaction and thus released into the atmosphere.

Detailed explanation-3: -During the process of photosynthesis, water is split in a process called photolysis. Photolysis is a process where sunlight energy is used to split water into oxygen and hydrogen molecules. Oxygen is then exhaled through the stomata and into the atmosphere.

Detailed explanation-4: -First, the PSII light receptor molecules capture light and excite molecules. This process leads to photolysis, as water molecules are broken into hydrogen and oxygen. The oxygen is released and the hydrogen builds up within the thylakoid membrane.

Detailed explanation-5: -Photolysis is the splitting of water molecules in the presence of light into proton, electron and oxygen. It takes place during non-cyclic photophosphorylation. The protons are used to reduce NADP and electrons are fed to photosystem II. Oxygen is released as a waste product.
