How does the amount of oxygen given off during photosynthesis compare to oxygen used during cellular respiration?
Question Date: 2020-01-25
Answer 1:

Hi Marlene, it seems as though the two systems are completely balanced. If an organism photosynthesizes 6 molecules of carbon dioxide it produces 6 molecules of oxygen. The same is true for cellular respiration, it requires 6 molecules of oxygen and, as a bi-product, produces 6 molecules of carbon oxidized. I found this cool YouTube video too!
