Metabolism is the sum of all the chemical processes or chemical reactions in the cells of living organisms that allows them to sustain life. Metabolism is the summation of 3 main functions: to convert food to energy , to convert food to building blocks for the body, and to eliminate metabolic waste . Metabolism, the sum of the chemical reactions that take place within each cell of a living organism and that provide energy for vital processes and for synthesizing new organic material. Living organisms are unique in that they can extract energy from their environments and use it to carry out activities such as movement, growth and development , and reproduction . Aug 11, 2015 · Biology on Khan Academy: Life is beautiful! From atoms to cells, from genes to proteins, from populations to ecosystems, biology is the study of the fascinating and intricate systems that make ... Notes over enzymes, energy, and metabolism as discussed in AP Biology. Includes a powerpoint presentation and enzymes showing active site, substrate and produces as well as a comparison of competitive and noncompetitive inhibition.
An energy-storage compound containing adenine, ribose, and three phosphate groups. When it is formed from ADP, useful energy is stored; when it is broken down (to ADP or AMP), energy is released to drive endergonic reactions. The energy input necessary for this work is either light, for photosynthesis, or the chemical potential energy of organic molecules. Work includes anabolic reactions, active transport and movement. Some organisms, such as mammals and birds, use thermal energy released from metabolic reactions to maintain their body temperature.

Sugar (chemical reactions) metabolism (a simple carbohydrate) is a classic example of the many cellular processes that use and produce energy. Living things consume sugar as a major energy source, because sugar molecules have considerable energy stored within their bonds.
