Microbial Metabolism : Utilization of Energy and Biosynthesis topics include: Energy utilization in biosynthetic and nonbiosynthetic processes, transcription and translation of genetic information and protein synthesis process. Microbial metabolism is the process by which microbes obtain energy and nutrients to live and reproduce. It involves a series of biochemical reactions that generate energy and use that energy to synthesize cellular materials.  Microbes can be classified based on the source of energy they use: Phototrophs: Use light as an energy source Chemotrophs: Use the oxidation...
