Document Summary
Compare and contrast autotrophs, heterotrophs, phototrophs, lithotrophs and chemotrophs. Differentiate and give examples of micronutrients and macronutrients. Compare and contrast facilitated diffusion and active transport. Identify different strategies used by cells to get nutrients across the plasma membrane. Identify and explain how the symports, antiports, abc transporters and group translocation systems work. Bacteria tend to absorb the nutrients from the surface they are surviving on. Every organism needs both carbon and energy. Bacteria and archaea support different methods of obtaining and utilizing energy and carbon. Microbes are classified and ranked based on how they aquire carbon and energy. Essential nutrients are extremely important for the growth and development of living things and must be supplied by the environment. Macronutrients are nutrients usually needed in larger quantities. There are also many ions important for protein function. Micronutrients are nutrients that are needed in lesser quantities. Trace elements that are necessary for enzymatic function include
