Answer 2

Energy from the Sun is used in PS II for the photolysis of water. (option a)

• The photosystem II is located in the thylakoid membrane of plants and algae. It is the first complex that recieves photons of light from the Sun.
• It has a reaction centre (P680) which obtains the photons with the help of surrounding light harvesting complexes.
• It is a part of the non-cyclic photophosphorylation and an important function is the splitting of water into hydrogen and oxygen, and electrons that are required in the ETC.
