Regulation of Intermediary Metabolism by Substrate Supply, Hormone Concentrations and Nervous Activity

摘要: Like many animals, humans shift between several major metabolic situations: absorption and postabsorption are determined by the individual pattern of food intake, rest exercise work loads imposed. Human energy turnover can vary about 90 W at 800 or 1500 a medium high load 150 300 W, respectively. Maintenance an adequate supply all tissues under these widely variable conditions is guaranteed very complex system regulation: most cells control substrate supply, circulating hormone local mediator concentrations activity nervous system.
