Glycolysis pathway enzymes and peripheral glucose utilization machinery

The glycolysis pathway enzymes and peripheral glucose utilization machinery encompass the series of proteins responsible for the transport of glucose into cells and its subsequent metabolic breakdown to generate energy (StatPearls, 2023). This system includes glucose transporters, such as GLUT4, which facilitate entry into muscle and adipose tissues, and key regulatory enzymes like hexokinase, phosphofructokinase, and pyruvate kinase (NCBI, 2021). In the context of metabolic disorders like type 2 diabetes, the machinery is often dysfunctional, leading to reduced peripheral glucose disposal and chronic hyperglycemia (PubMed, 2019). Conversely, in oncology, the upregulation of these enzymes—a phenomenon known as the Warburg effect—allows cancer cells to sustain high rates of proliferation even in aerobic conditions (Nature Reviews Cancer, 2008). Therapeutic strategies targeting this machinery range from insulin sensitizers like Metformin that promote glucose uptake to glycolytic inhibitors like 2-Deoxy-D-glucose designed to selectively starve tumor cells (PubChem, 2024).
