[Regulatory properties of digestive enzymes and the biology of multiple substrate digestive processes].

Characteristics of functional organization and autoregulation of natural polysubstrate digestion in various animals are largely defined by regulatory properties of the enzymes ensuring membrane digestion. This has been demonstrated for both the animals which are at different evolutional levels and those specialized for different types of food. The effective organization of the digestive and transport processes in time and space is provided by an interaction of food substances at the stage of membrane digestion.
