Glucose metabolism refers to the biochemical processes that break down glucose to produce energy, primarily in the form of ATP (adenosine triphosphate). This essential pathway involves various stages, including glycolysis, the Krebs cycle, and oxidative phosphorylation, which collectively transform glucose into usable energy for cellular functions. Understanding glucose metabolism is crucial because it connects energy production to brain function and neural activity, making it a vital aspect of neuroimaging techniques that assess brain activity based on metabolic changes.
