You are conducting a dialysis experiment to observe the rate of movement of a specific protein, called Protein A, across the semipermeable dialysis tubing membrane. Assuming that there is no Protein A in the aqueous solution in which the dialysis tubing is placed, the concentration of Protein A in the dialysis tubing is 6 mM and the size of the pores in the dialysis tubing are large enough to permit the movement of Protein A, in which direction would you expect Protein A to migrate?
a. The direction of movement depends upon the size of the dialysis tubing pores
b. Towards equilibrium
c. Along its concentration gradient
d. Into the dialysis tubing from the aqueous solution
e. Out of the dialysis tubing and into the aqueous solution
