Document Summary
Metabolism: the chemical processes that occur within a living organism in order to maintain life. Catabolism: breakdown of large molecules followed by the release of energy. Muscle breakdown, digestion, fat fatty acids, glucose energy. Anabolism: synthesis of larger molecules from smaller ones, requiring an input of energy that is obtained from catabolic reactions. Growth, glucose glycogen, fatty acids fat, muscle building. Enzymes: biological molecules that speed up chemical reactions. Have organic partners called coenzymes that assist in chemical reactions. In the cell, energy transformation depends on oxidation-reduction reactions. Oxidation: the loss of an electron (or hydrogen atom) Reduction: the gain of an electron (or hydrogen atom) Energy metabolism: chemical reactions involved in storing fuels or breaking them down to produce atp. Cellular respiration: process where the energy stored in fuels is transferred to atp by a series of enzyme-catalyzed reactions. Metabolic pathways by which energy is released and used to produce atp.
