When exposed to light, plant cells show a net absorption of CO2 and net production of O2. In the dark, they show net production of CO2 and net absorption of O2.
a. What biochemical process is responsible for the plants absorption of O2 and net production of CO2?
b. Does this process continue when the plant is exposed to light? If so, why aren't net production of CO2 and net absorption of O2 seen under these conditions? Explain briefly.
