The value of RQ at compensation point is
unity
infinity
> 1
zero
D.
zero
The (light) compensation point is the light intensity on the light curve where the rate of photosynthesis exactly matches the rate of cellular respiration. At this point, the uptake of CO2 through photosynthetic pathways is equal to the respiratory release of carbon dioxide, and the uptake of O2 by respiration is equal to the photosynthetic release of oxygen.
In assimilation terms, at the compensation point, the net carbon dioxide assimilation is zero. Leaves release CO2 photorespiration and cellular respiration, but CO2 is also converted into carbohydrate by photosynthesis. Assimilation is therefore the difference in the rate of these processes. At a normal partial pressure of CO2, there is irradiation at which the net assimilation of CO2 is zero.
