Metabolic Regulation

Abstract

The principles of metabolic regulation are described in the context of the major metabolic pathways of the liver. In the fed state, increased plasma insulin initiates a signaling cascade that enhances flux through pathways that promote glycogen and triacylglycerol synthesis. This is achieved by well-coordinated regulation of key enzymes by allosteric effectors, covalent modification, inhibitory protein interaction, and altered gene expression. In the fasting state, increased plasma glucagon activates a signaling cascade that enhances glycogenolysis, gluconeogenesis, and ketogenesis. Regulation of key enzymes plays a central role in enhancing the flux in the metabolic pathways to maintain energy homeostasis and glucose homeostasis.
