Question:
The conversion of CO2 into carbohydrates by plants via photosynthesis can be represented by the reaction
To study the mechanism of photosynthesis, algae were grown in water containing 18O, that is, H218O. The oxygen evolved contained oxygen-18 in the same ratio to the other oxygen isotopes as the water in which the reaction was carried out. In another experiment, algae were grown in water containing only 16O, but with oxygen-18 present in the CO2. The oxygen evolved in this experiment contained no oxygen-18. What conclusion can you draw about the mechanism of photosynthesis from these experiments?
