Pmax: The maximum pressure of oxygen gas. 2. Arbitrary units: The use of this term mean the graph is not using specific units as labels. Light intensity could be measured in lumens and oxygen production could have been measured in mm of Hg elect the best explanation for the oxgen production leveling off as the light increases in intensity. O More light reduces the activity of the chlorophyll by breaking the pigment down. More light prevents water from getting to the leaf cells to be split.
