Question

Scientists often add radioactive atoms to reactants in order to see what products the atoms end up in. The chemical reactions for photosynthesis is H2O + CO2 ------> C6H12O6 + O2 + H2O. If the input water is labeled with a radioactive isotope of oxygen, then the oxygen gas released as the reaction proceeds contains the radioactive oxygen. Which if the following is the most likely explanation?

Answer 1

Photosynthesis is the process of formation of food from the soil, water, carbon and light. The light reaction is converted into the chemical reaction during photosynthesis.

The radioactive elements is used for the study of the biochemical reaction and the normal chemical reactions. The light reaction involves the splitting of the water molecule that release the hydrogen and oxygen gas. The oxygen can be traced as the oxygen is radioactively labelled in the reactions.
