Answer:
from the splitting of water molecule.
Explanation:
The splitting of water molecules by sunlight is called Photolysis. This is the first reaction in photosynthesis; which occurs by catalysis of enzymes of Photo system 11.
It involves the splitting of water molecules into;
hydrogen ion/protons.
Oxygen
and electron.
<u> Oxygen is the by product liberated into the atmosphere, for animals to inhale for the process of cellular respiration</u><u>.</u>This is the source of oxygen fro cellular respiration in animals.
the hydrogen ions combined with electrons from photosystem 1 to reduce NADP .The latter is used to reduce C02 to form carbohydrate in light independent reaction
