5. If the light intensity and carbon dioxide levels are kept
constant (at their most efficient levels), increasing the air temperature around
the plant would affect the reaction rate for photosynthesis in the following
way:
The higher the temperature the faster the reaction (the enzymes
work faster at warmer temperatures due to increased and more forceful collisions).
At some point, increasing the temperature has no affect (the rate doesn't increase)
because above that temperature, photosyntheis is working at its maximum rate.
