BIOL 3361 BIOCHEMISTRY I METABOLISM Know the classification of organisms by their energy source Phototrophs : use light as energy source Chemotrophs : use chemical compounds as energy sources o Chemoorganotrophs : use organic compounds o Chemolithotrophs : use inorganic compounds Know the classification of organisms by their carbon source Autotrophs : use CO 2 as carbon source Heterotrophs : use organic compounds as carbon source Understand the meanings of the words metabolism , catabolism and anabolism Metabolism : nutrients are not converted into energy, rather metabolism allows the energy in nutrients (or light) to be captured (conserved) in forms (typically ATP and proton motive force) that can be used to do work in the cell Catabolism allows the energy of nutrients to be captured in forms that can do work in the cell, principally ATP, NADH, NADPH and the proton motive force Catabolism : oxidative degradation of complex organic nutrients to simpler oxidized energy-poor
