Abstract

Both processes involve extremely large amplification between the stimulus and the response. In vision it had been suggested that thismight be achieved by a chain of successive proenzyme-enzyme activations. Such a chain has now been found to underlie the mechanism of blood clotting. Methods are suggested for pursuing this comparison further.
