The rate in which photosynthesis occurs is dependent upon three main variables: light, Carbon dioxide (CO2) concentrations, and temperature. How would the process of photosynthesis be affected, and in what steps, if light, CO2 concentration, and/or temperature were altered during photosynthesis? • Show less
