Can we consider oxygen as a product of light dependent reactions?
2 Answers
Yes!
Explanation:
Oxygen is in fact a by product of light dependent reactions of photosynthesis.
During light reaction of photosynthesis, In non-cyclic electron flow, when Photosystem II absorbs light, an electron is excited to a higher energy level in the reaction center of Chlorophyll
Thus an enzyme extracts electron from water, splitting the water molecule into two hydrogen ions and one oxygen atom. The oxygen atom abrubptly combine with another oxygen atom to form
Hope it helps!
Oxygen is normally considered a byproduct or waste product of the light dependent reactions since it isn't involved in the reactions of photosynthesis.
Explanation:
However, oxygen is a very valuable by/waste product, since all aerobic organisms require it for aerobic cellular respiration, including plants.
The image below shows the light independent reactions of photosynthesis at the thylakoid membrane of the chloroplast.
