Computer Solutions for Photosynthesis Rates from a Two Pigment Model
A kinetic model for a two pigment mechanism of photosynthesis based on observations made on the red alga Porphyridium cruentum is developed. The model supposes that different products are formed by chlorophyll and phycobilin pigments and that these products react to produce oxygen. The product of th...

Summary: | A kinetic model for a two pigment mechanism of photosynthesis based on observations made on the red alga
Porphyridium cruentum is developed. The model supposes that different products are formed by chlorophyll and phycobilin pigments and that these products react to produce oxygen. The product of the chlorophyll reaction is also rapidly utilized for O
2 consumption both in light and in the dark. Rate equations based on the model reactions were derived and put into an analog computer. The effect of varying parameters on the time course curves for oxygen exchange resulting from the model was studied. Appropriate selection of parameters yielded computer curves which resembled fairly closely the oxygen exchange curves obtained using
Porphyridium. The model showed the Emerson enhancement effect, chromatic transients, “respiratory stimulation,” and other effects observed with live algae. |
