Photosynthesis Directory
... isotope of oxygen, only the lighter isotope was emitted from the plant as oxygen gas. However, if the oxygen of the water was labelled, so was the oxygen gas emitted. This showed that the oxygen for photosynthesis was derived from the water. Light energy entering the plant splits the water into hydrogen and oxygen: H2O + light ...

... Cycle). When the two atoms of hydrogen join with NADP, oxygen is liberated, and this is the source of oxygen gas in our atmosphere. ATP and NADPH2from the light reactions are ... some intestinal gas, particularly the combustible component of flatulence. They produce methane gas anaerobically (without oxygen) by removing the electrons from hydrogen gas. The electrons and H+ ions from hydrogen gas are ...
