Which molecule is the oxygen derived from photosynthesis?

Answer 1

The oxygen plants give off is from water.

Two water molecules are broken apart inside the thylakoid space during the light reactions. The two oxygen atoms bond together to form molecular oxygen and the four hydrogen molecules help build up a gradient that will be used in chemiosmosis (a process that uses hydrogen to make energy similar to what a dam does).

Answer 2

Its actually the combination of water H2O and carbon dioxide CO2. Photosynthesis produces food energy in the form of glucose C6H12O6 for the plant. The actual formula 6 H2O + 6 CO2 = C6H12O6 + 6O2. It takes 6 water molecules and 6 carbon dioxide molecules to produce a single glucose molecule with six oxygen molecules left over as a by product.

Answer 3

The oxygen released during photosynthesis is derived from water molecules (H2O) that are split during the light-dependent reactions of photosynthesis.

Answer 4

I believe it is derived from water
