1. A protein was observed to move 300 µm in 12.7 minutes at 23°C. Assuming its density and viscosity to be 1.34 g/cm3 and 0.89 X 10-2 g/cm s respectively, calculate the following parameters related to the protein's shape and its movement.
a. Diffusion coefficient
b. Friction coefficient
c. Radius
d. Volume
e. Molar weight
