Question 6

Up until the 1930s it was assumed that the carbohydrates plants produced resulted from the combination of carbon atoms with water,and the oxygen released came from the splitting of the carbon dioxide molecule.You are a scientist testing this hypothesis.You have available to you water labeled with radioactive oxygen atoms and carbon dioxide labeled with radioactive oxygen atoms.Design an experiment to determine whether the oxygen produced during photosynthesis comes from the splitting of carbon dioxide or the splitting of water.
