It reduces H2O into H+ and O
|
|
|
O2 is actually generated in the Calvin Cycle
|
|
|
It Oxidizes H2O into H+ and O
|
|
|
Oxygen atoms are assembled in Photosystem II
|
Detailed explanation-1: -Photosystem II is the first membrane protein complex in oxygenic photosynthetic organisms in nature. It produces atmospheric oxygen to catalyze the photo-oxidation of water by using light energy. It oxidizes two molecules of water into one molecule of molecular oxygen.
Detailed explanation-2: -The two electrons lost from photosystem II are replaced by the splitting of water molecules. Water splitting also releases hydrogen ions into the lumen.
Detailed explanation-3: -Answer and Explanation: The important component of photosystem 2, is the ability to absorb light energy to generate high energy electrons for the electron transport chain. Specifically, photosystem 2 will oxidize water to produce these high energy electrons.
