Metabolism regulation is the process by which living organisms control their metabolic pathways in order to maintain homeostasis and adapt to changing environmental conditions. It involves the regulation of biochemical reactions that convert nutrients into energy and building blocks for cellular processes. This can involve the activation or inhibition of enzymes, the control of metabolic flux through signaling pathways, and the coordination of different metabolic pathways within the cell. Dysregulation of metabolism can lead to various diseases such as diabetes, obesity, and cancer. Understanding and manipulating metabolism regulation is therefore essential for developing treatments for these diseases and optimizing metabolic function for health and performance.
