Document Summary
Independent study guide - metabolism: principles of metabolism (section 6. 1) the sum of all chemical reactions in a cell. Harvest energy and convert it to a usable form (catabolism) If the starting compounds have more free energy than the products, energy is released; the reaction is exergonic. If the products have more free energy than the starting compounds, the reaction requires an input of energy and is endergonic. Components of metabolic pathways (figure 6. 4) the series of chemical reactions that converts a. Starting compound to an end product is called a metabolic pathway. Branched, or cyclical and can be adjusted at certain points to allow the cell to regulate. The role of enzymes (figure 6. 5) an enzyme is a molecule (usually a protein) that functions. As a biological catalyst, speeding up the conversion of one substance, the substrate, into. An enzyme catalyzes a chemical reaction by lowering the activation. Energy the energy it takes to start a reaction.
