Metabolic Pathway
A Metabolic Pathway is a Biochemical Reaction Series that occur in a living cell.
- AKA: Metabolic Path.
- Context:
- It can reflect Protein-Protein Interactions in order to accomplish some Biological Function.
- See: Metabolism, Catabolism, Cell (Biology), Metabolites, Chemical Reaction, Catalyze, Enzyme, Product (Chemistry), Substrate (Chemistry), Cofactor (Biochemistry), Homeostasis.

- In biochemistry, a metabolic pathway is a series of chemical reactions occurring within a cell. The reactants, products, and intermediates of an enzymatic reaction are known as metabolites. In a pathway, the reactant is modified by a sequence of chemical reactions. These reactions are catalyzed by enzymes, where the product of one enzyme acts as the substrate for the next. These enzymes often require dietary minerals, vitamins, and other cofactors to function.
Different metabolic pathways function based on the position within a eukaryotic cell and the significance of the pathway in the given compartment of the cell. For instance, the citric acid cycle, electron transport chain, and oxidative phosphorylation all take place in the mitochondrial membrane. In contrast, glycolysis, pentose phosphate pathway, and fatty acid biosynthesis all occur in the cytosol of a cell.
Pathways are required for the maintenance of homeostasis within an organism and the flux of metabolites through a pathway is regulated depending on the needs of the cell and the availability of the substrate. The end product of a pathway may be used immediately, initiate another metabolic pathway or be stored for later use. The metabolism of a cell consists of an elaborate network of interconnected pathways that enable the synthesis and breakdown of molecules (anabolism and catabolism)
