Cellular glucose metabolism

Cellular glucose metabolism refers to the complex series of biochemical reactions through which cells ingest, transport, and break down glucose to generate energy in the form of adenosine triphosphate (ATP) (StatPearls, 2023). This process encompasses several interconnected pathways, including glycolysis, the pentose phosphate pathway, and oxidative phosphorylation, which are essential for maintaining systemic energy homeostasis (NIH/NCBI). Beyond energy production, these pathways provide crucial carbon skeletons for the synthesis of amino acids, lipids, and nucleotides. Dysregulation of glucose metabolism is a hallmark of numerous diseases, most notably type 2 diabetes, where insulin resistance leads to hyperglycemia, and cancer, where the Warburg effect describes a metabolic shift toward aerobic glycolysis to support rapid proliferation (PubMed/Wikipedia). Pharmacological interventions often target specific nodes within this process, such as glucose transporters (GLUTs) or rate-limiting enzymes like hexokinase, to restore metabolic balance or selectively inhibit pathological cell growth (PubChem).

Drugs modulate this pathway by activating or inhibiting specific enzymes (e.g., AMPK activation by metformin), transporters (e.g., SGLT2 inhibition), or hormonal receptors (e.g., insulin receptor) to regulate glucose uptake, hepatic production, and systemic levels.
