Metabolic Regulation
The coordinated control of metabolic pathways through enzymatic, hormonal, and cellular mechanisms to maintain physiological homeostasis while adapting to changing energy demands.
Metabolic Regulation
Overview
Metabolic regulation represents a sophisticated example of dynamic equilibrium in biological systems, where multiple biochemical pathways are continuously adjusted to maintain cellular homeostasis while responding to environmental changes and physiological demands. This regulation operates through multiple levels of control, from molecular to organismal scales.
Fundamental Mechanisms
Enzymatic Control
- allosteric regulation of key enzymes
- feedback inhibition
- substrate-level control
- covalent modification (phosphorylation/dephosphorylation)
Hormonal Regulation
- insulin - glucose uptake and storage
- glucagon - glucose mobilization
- epinephrine - emergency energy mobilization
- thyroid hormones - metabolic rate control
