General cellular metabolic and antioxidant pathways

General cellular metabolic and antioxidant pathways encompass the integrated network of biochemical reactions responsible for energy transduction and the maintenance of redox equilibrium. These systems include central metabolic routes such as glycolysis and the tricarboxylic acid (TCA) cycle, as well as enzymatic antioxidant defenses like superoxide dismutase and the glutathione system (NIH, 2023). These pathways are fundamental to cellular survival, providing the building blocks for biosynthesis and neutralizing reactive oxygen species (ROS) generated during respiration. Dysregulation of these processes is a hallmark of various diseases; for instance, cancer cells often exhibit metabolic reprogramming (the Warburg effect) to support rapid growth, while oxidative stress is a primary driver of neuronal loss in neurodegenerative conditions (PubMed, 2022). Because this term refers to a broad physiological framework rather than a single protein or receptor, it is not classified as a discrete therapeutic target. Instead, pharmacological strategies typically focus on modulating specific rate-limiting enzymes or transporters within these pathways to achieve a therapeutic effect (StatPearls, 2023).
