Consider an imaginary bacterial cell that contains equal concentrations of 800 different enzymes in solution in the cytosol. Each protein has a molecular weight of 110000 . The cytosol has a specific gravity of 1.24 and contains 22.2% soluble protein by weight (the protein fraction consists entirely of enzymes). Calculate the molar concentration of each enzyme in this cell.
