A nutrient has a Mw 42, 000g/mole diffuses The pores of the membrane are cylindrical, the nutrition is sperical. The pores have a diameter of 32 nm and an overall length of 325um. The thickness of the membrane is 250um. The pores of the membrane comprise 40% of the membrane volume. Assume the nutrient enters the membrane from a well-stirred bulk water solution that is at 37C. Calculate the radius of the nutrient. (landa)=a/r . Kwr Would you expect any changes in permeability if the nutrient is diffusing through blood?
