Melvin Calvin used which radioactive isotope to trace the path of carbon in algal photosynthesis?
Show answer and explanation
Correct answer: 14C
Melvin Calvin and his coworkers used the radioactive isotope 14C in algal photosynthesis studies. This allowed them to identify the first carbon fixation product and map the entire pathway.
