r^2=6Dt , where D is the diffusion coefficient of thediffusing object and t is the time that the object is allowed to diffuse. If the diffusion coefficient, D, of a small protein is 5 x 10^-10 m2 s-1, how long (on average) does ittake for the protein to diffuse across a parasitic wasp that is 189 um long ?
A new 850 cm^2 membrane is being tested for use in a hemodialysis device. During testing, a model fluid mixture is used that contains solutes with average radii of 1 nm. In one test, the concentration of the filtrate is found to be 2.17 g/L, while the concentration on the feed-side surface is 8.52 g/L. Prior experimentation showed that the mass transfer coefficient in the device was approximately 9 × 10-4 cm/s. A) If the total filtration flow rate is measured to be 0.56 cm^3/s, what is the solute concentration in the feed solution? B) Explain how you could determine the average membrane pore radius for this membrane using this information.
Infuse heparin at 1,200 units per hour from a solution containing 40,000 units of heparin in 500 mL D5W. How many mL/hr will deliver the ordered dosage?
• Estimation of the Water Potential (Ψw) of Storage Tissue by Volume Change Method Observe these experiments in these links: https://www.youtube.com/watch?v=jTDATlaBV-o https://www.youtube.com/watch?v=k1O9jBHgsxs Estimates of water potential of various tissues have been obtained after equilibrating the tissues in solutions of different osmotic potentials. The principle depends upon finding the concentration of sucrose that would cause no change in weight of the tissue before and after an incubation period in the solution. This concentration may be assumed to have a water potential equal to that of the tissue.

The toxic effect of Na+ ions can be avoided in some plant species by storing them in membrane-bound vacuoles within the cytosol. Calculate the maximum vacuolar-to-cytosolic [Na+] ratio that could be achieved by a Na+/H+ antiport mechanism in the vacuolar membrane if the cytosolic pH is 7.4 and the vacuolar pH is 5.6.
