Question

think and answer. 3 oxygen is released during photosynthesis in Green plants. this oxygen comes from water . do you agree? if not, from where this oxygen comes? ​

Answer 1

Answer:

fully agreed

Explanation:

Photolysis takes place in the light dependent reaction of the photosynthesis. The reaction can be represented as:

H2​O + 2 photons --> 2 e− + 2H+ + O.

Here, the electrons released are accepted by the photosystem to fulfill the electron gap. The last electron acceptor is the oxygen and thus, the oxygen is liberated from the water molecule. The experiments conducted by Samuel Ruben and Martin Kamen by using radioactive isotopes helped to prove that the oxygen liberated during photosynthesis came from photolysis the water.
