Glucose metabolism is a fundamental physiological process essential for energy production and maintaining blood glucose homeostasis. This article provides an overview of glucose metabolism, highlighting key pathways such as glycolysis, the citric acid cycle, and oxidative phosphorylation. It also covers gluconeogenesis, glycogen metabolism, and the hormonal regulation of glucose levels. Understanding these processes is crucial for managing metabolic disorders like diabetes mellitus, where dysregulation can lead to significant health issues. This synthesis of glucose metabolism aims to provide a clear and comprehensive understanding of how glucose is processed within the body.
