Processing time of an absorbed photon by the chemical reactions leading to CO2 fixation

Value 5 millisec
Organism Plants
Reference Nobel, P. S. "Plant Physiology", 3rd ed. p.243 3rd paragraph
Comments P.243 3rd paragraph: "The electron excitation caused by the absorption of a photon can be processed by the chemical reactions leading to CO2 fixation about once every 5×10^−3 s (5 ms). This processing time has important consequences for both the efficiency of light use at different photon flux densities and the optimal number of chlorophylls per reaction center." Governs the maximal rate of photon harvesting performed by a reaction center ~200Hz
