Abstract
The effect of illumination on the rate of uptake of 02 isotopes by R. rubrum was studied manometrically and with a mass spectrometer using tracer O2 in the gas phase. Light decreased the rate of O2 consumption. Photoinhibition usually was incomplete and amounted to 60-85% in most experiments. No molecular O2 was produced in the light; therefore the effect on respiration was a true inhibition of O2 consumption rather than photosynthesis compensating for respiration.This publication has 4 references indexed in Scilit:
