Glucose metabolism refers to the process by which the body breaks down and uses glucose, a type of sugar that serves as its primary source of energy. This involves several steps, including the uptake of glucose from food into cells, its breakdown through glycolysis or other pathways, and the production of ATP (adenosine triphosphate), which is used to power cellular processes. Glucose metabolism also includes the regulation of blood sugar levels by hormones such as insulin and glucagon, which help control how much glucose is available in the bloodstream for use by cells. Overall, glucose metabolism is a critical process that enables the body to function properly and maintain energy balance.
