Document Summary

Energy sources: many diff energy sources are funneled into common degradative pathways, most pathways generate glucose or intermediates of pathways used in glucose metabolism, few pathways greatly increase metabolic efficiency. Requirements for c, h, and o: often satisfied together. Carbon source often provides h, o, and electrons: heterotrophs. Use organic molecules as carbon sources which often also serve an energy source. Can use a variety of carbon sources. Needed for most functions and molecules: autotrophs. Use carbon dioxide as their sole or principle carbon source. Nutritional types of organisms: based on energy source. Chemotroph obtain energy from oxidation of chem compounds (organic or inorganic: based on electron source. Organotrophs obtain electrons from organic compounds: photolithoautotrophs, photoorganoheterotrophs, chemolithoautotrophs, chemolithoheterotrophs, chemoorganoheterotroph. Fueling reactions: despite diversity of energy, electron and carbon sources used by organisms, they all have the same basic needs. Reducing power to supply electrons for chemical reactions. Chemoorganotrophic fueling processes: also called chemoheterotrophs, processes.
