Metabolism: Part 1

Watch this video for an overview of the metabolic process. It describes the two major kinds of metabolic pathways: linear and cyclical. Pay attention to the descriptions of catabolic and anabolic pathways in cellular metabolism. Catabolism breaks down molecules (creates energy), while anabolism assembles molecules (requires energy). You should also be able to define the components of a metabolic pathway: reactants (substrate molecules), intermediates (intermediate substrates), and the final products.
