The Calvin cycle represents the light-independent set of photosynthetic reactions affected by light intensity, availability, and temperature.
It is the process that uses adenosine triphosphate (ATP) and NADPH generated during light-dependent reactions to convert atmospheric CO2 into complex carbohydrates.
Therefore, we can conclude that at the beginning of the Calvin cycle, atmospheric CO2 enters the leaf through the stomata, a process that would be affected by light intensity, availability and temperature.
