Solution
The correct option is B C14O2
Using the technique of autoradiography, Calvin found that C-14 turned up in glucose molecules within 30 seconds after the start of photosynthesis. When he permitted photosynthesis to proceed for only 5 seconds, however, the radioactivity was concentrated in several other, smaller molecules.
