An analog model of the photosynthesis-light curve is presented and applied to published data. Previous equations have been constructed with parameters having geometric rather than biologic definition. The present study defines each parameter as an analog of a hypothetical photosynthetic system. The model is constructed of two stages, a light stage composed of photosynthetic factories, N, with probability P of intercepting a given amount of light, and a dark stage approximated by the Michaelis-Menten equation. An index of the speed of the dark stage, relative to the potential speed of the light stage is provided. The model describes a family of photosynthesis-light curves and can be applied to data to interpret changes in the photosynthetic system from changes in the shape of the curve.
