You are surprised to observe that the patient's thrombin flows through the cm-cellulose column at ph=6.4 faster than expected based on its pi. confident in your technique, you suspect the patient's thrombin is different from wild-type thrombin. using a different buffer system, you manage to purify some of the patient's thrombin and you submit the purified sample for amino acid sequencing. the sequence analysis shows that the patient's thrombin contains a mutation in the enzyme active site. a lysine residue in the wild type has been mutated to an asparagine in the patient's thrombin. does this mutation explain the anomalous cm-cellulose binding behavior you observed?

4.) metal

"-the movement of carbon from the nonliving environment into living things and back to the environment

-carbon is the essential component of proteins, fats, and carbohydrates (which make up all organisms)

-carbon exists in air, water, and living organisms

-producers convert carbon dioxide in the atmosphere into carbohydrates during photosynthesis

-bacteria in the atmosphere cycles through the system in filtration units

-in cellular respiration, carbon is released back into the atmosphere as carbon dioxide

-some carbon is stored in limestone (forming one of the largest "carbon sinks" on earth)

-largest carbon reservoir on earth= limestone

-carbon stored in the bodies of organisms as fat, oils, or other molecules may be released into the soil or air when the organism dies

-this may form deposits of coal, oil, or natural gas (fossil fuels, which increased the atmospheric carbon dioxide)

-fossil fuels store carbon left over from bodies of organisms that died millions of years ago

-they are located in the surface of earth, deep within the earth and beneath the ocean floor."
