What is the purpose of splitting water in PS2 of the light dependent reaction?
|
|
Provides e-for PS2 and H+ for the thylakoid space
|
|
|
To produce Oxygen for animals
|
|
|
There is no purpose
|
Explanation:
Detailed explanation-1: -The electron transport chain moves protons across the thylakoid membrane into the lumen. At the same time, splitting of water adds protons to the lumen while reduction of NADPH removes protons from the stroma.
Detailed explanation-2: -During Light reactions of Photosynthesis, the chlorophyll will be activated by light. This light activated chlorophyll will split the water molecule. This process is called Photolysis. Water molecule is split to release H+ ions and also oxygen.
Detailed explanation-3: -Photosystem 2 (PS2) is the part of the photosynthetic apparatus that uses light energy to split water releasing oxygen, protons and electrons.
