a. Glucose is present in bacterial cells at a concentration ofabout 1 mM. What is the concentration of glucose expressed asmg/mL? How many molecules of glucose are contained in a typical E.coli cell (assuming that E. coli is in a cylindrical shape).
b. A number of regulatory proteins are present in E.coli at only 1or 2 molecules/ cell. If we assume that an E. coli cell contains just one molecule of a particular protein, what is the molar concentration of this protein in the cell? If the molecular weight of this protein is 40 kD, what is its concentration expressed as mg/mL?
