Regulation of metabolism constitutes a significant part of biochemistry concerning how cells may regulate metabolic pathways to achieve homeostasis and adaptation. Such includes coordination of various biochemical reaction pathways wherein there is generation as well as utilization of energy and synthesis of vital molecules along with degradation of waste products.

The primary regulators of metabolism are enzymes, which are considered as biological catalysts that hasten the metabolic reactions.

Enzyme activity is strictly controlled by allosteric regulation, covalent modification, and feedback inhibition among others. Allosteric regulation involves binding molecules at locations away from the active site of an enzyme to regulate its activity. Covalent modification includes phosphorylation among others. It may activate or inhibit enzymes. An end product of a metabolic pathway regulates an earlier step by a process called feedback inhibition so that excessive accumulation of substances is checked.

Regulation of hormones is also very critical in regulating metabolism. Insulin, glucagon, and adrenaline hormone play a signaling role with regard to such metabolic processes by signaling cells to adjust their activity. For example, insulin stimulates glucose uptake and storage, while glucagon stimulates the release of glucose into the bloodstream. The regulation of metabolism has a very significant role with respect to health and disease. Dysregulation leads to disorders such as metabolic diabetes and obesity, and even cancer. This area of research helps to develop therapeutic strategies that control such conditions and optimize metabolic health.
