 PHOTOSYNTHESIS

Blackman: 1920s

Experiment 2 Light Intensity and CO2 Concentration

 

  (Note ambient [CO2] = 0.035% or 350 ppm)
Observation CO2 limits the rate of photosynthesis at high light
intensities (C) i.e. when light is not a limiting factor.
Conclusion Carbon fixation takes place in the Light Independent Reaction
It is an enzyme controlled process
