|
|
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: -The sunlight energy obtained by Photosystem II is used to extract electrons from water molecules through certain proteins and enzymes. Two water molecules break into oxygen gas and hydrogen ions, and the freed oxygen gas is the source of oxygen available for us to breath.
Detailed explanation-2: -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-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.
