Abstract
In biochemistry, metabolic pathways are series of chemical reactions occurring within a cell. In each pathway, a principal chemical is modified by a series of chemical reactions. Enzymes catalyze these reactions, and often require dietary minerals, vitamins, and other cofactors in order to function properly. Because of the many chemicals (a.k.a. "metabolites") that may be involved, metabolic pathways can be quite elaborate. In addition, numerous distinct pathways co-exist within a cell. This collection of pathways is called the metabolic network. Pathways are important to the maintenance of homeostasis within an organism. Catabolic (break-down) and Anabolic (synthesis) pathways often work interdependently to create new biomolecules as the final end products. A metabolic pathway involves the step-by-step modification of an initial molecule to form another product. The resulting product can be used in one of three ways: To be used immediately, as the end-product of a metabolic pathway To initiate another metabolic pathway, called a flux generating step. To be stored by the cell A molecule called a substrate enters a metabolic pathway depending on the needs of the cell and the availability of the substrate. An increase in concentration of anabolic and particular pathway catabolic intermediates and / or end - products may influence the metabolic rate for that Overview Each metabolic pathway consists of a series of biochemical reactions that are connected by their intermediates the products of one reaction are the substrates for subsequent reactions, and so on. Metabolic pathways are often considered to flow in one direction.
