What did Hill, Calvin, and other researchers discover separately about the locations of the events in photosynthesis?

A. Oxygen, ATP, and NADPH are produced in the thylakoids of the chloroplasts in a reaction that does not require light; carbon fixation takes place in the stroma of the chloroplast in a reaction
that requires light.
