单选题 To approximate the concentration of enzymes in a human cell, assume that the cell contains equal concentrations of 1,000 different enzymes in the cytosol and that each enzyme has a molecular weight of 100,000. Assume also that the cell is a ball (diameter 30 μm), that the cytosol (specific gravity 1.20) is 20% soluble protein by weight, and that the soluble protein consists entirely of enzymes. Calculate the average molar concentration of each enzyme in this hypothetical cell

C. 2.4 × 10-6 M

D. 2.4 × 10-7 M
