how is oxygen produced during the light reactions of photosynthesis and what happens to it?

Answer 1

Light energy chemically "excites" chlorophyll molecules. The energized chlorophyll separates water molecules into hydrogen and oxygen by a process called photolysis. The oxygen is liberated into the atmosphere via stomata . The hydrogen becomes part of the dark reactions/Calvin cycle.

Answer 2

6 CO2 + 12 H2O + light → C6H12O6 + 6 O2 + 6 H2O
Light excites the chlophyll, which loses an electron. In other words, it's "reduced". The source of oxygen during photosyntehsis isn't the carbon dioxide, but the water. The chlorophyll (which lost an electron) attacks the water, gaining two electrons. But now the water molecule is unstable. Oxygen lost 2 electrons to the chlorophyl, and it has two hydrogens bonded to it. It's clearly unhappy. So in order to become happy, it wants to lose the two hydrogens. Bam. Now it's 1/2 a molecule of oxygen gas.

So Oxygen is evolved.

Answer 3

Photosynthesis is the technique interior which vegetation use water and carbon dioxide to grant sugars and oxygen. Skeleton equation power* + carbon dioxide + water = sugar + oxygen + power* chemical equation e* + CO2 + H2O = C6H12O6`` + O2^ + e* balanced chemical equation e* + 6 CO2 + 6 H2O = C6H12O6`` + 6 O2^ + e* NOTES * e is capability; it extremely is no longer a tangible reactant or product, even if you may write it in. `` C6H12O6 is the least confusing sugar, glucose, and so we use that when modelling photosynthesis. ^ oxygen is a diatomic molecule, meaning while it extremely is a gasoline, there is in any respect circumstances 2 jointly, so we ought to write down it this style.
