Cellular metabolism comprises interconnected reactions that generate energy, supply biosynthetic precursors, transform endogenous and foreign molecules, and maintain redox balance. Nutrient use and mitochondrial activity connect carbohydrate, lipid, amino-acid, nucleotide, and cofactor metabolism with signaling and cellular state. These processes are studied across physiology, toxicology, cancer biology, and metabolic research.
The extensive taxonomy is organized by enzymes, receptors, transporters, and metabolite classes. Populated areas include cytochrome P450 enzymes, nuclear receptors, dehydrogenases, lipid-processing enzymes, glycolytic targets, oxidative phosphorylation, mitochondrial metabolism, and endogenous or drug metabolites. The grid supplies the detailed target navigation; this introduction defines the shared metabolic context without implying that all entries form one pathway.
