Despite this impressive radiation, bacteria are still limited by the availability of carbon and nitrogen sources for their metabolisms. Bacteria may express many different proteins required for uptake and utilization of these compounds for use in their metabolisms. Organic compounds containing carbon and nitrogen are required for both anabolic and catabolic reactions that comprise a cell’s metabolism. Not all bacterial species have the same abilities, so you can use this characteristic to differentiate bacterial species by determining which carbon- and nitrogen-containing media support the growth of the bacteria. Determine whether the following enzymatic reactions are anabolic or catabolic and place them within the correct bin. 1. Glucose is broken down into two pyruvates 2. ammonia is added to glutamate to form glutamine 3. four amino acids are linked together to form tetrapeptide 4. a uracil base is added to a mRNA strand by RNA polymerase 5. starches are digested into individual glucose molecules 6. ribose and inorganic phosphate are bonded to form a nucleotide base • Show less
