Show transcribed image text Protein diffusion. The diffusion coefficient, D. of a rigid spherical molecule is given by D = k T/6pi eta r in which eta is the viscosity of the solvent, r is the radius of the sphere, k is the Boltzman constant (1.38 Times 10^16 erg degree^-1), and T is the absolute temperature. What is the diffusion coefficient at 37 degrees C of a 100-kDa protein in a membrane that has an effective viscosity of 1 poise (1 poise = 1 erg s^-1 cm^-3)? What is the average distance traversed by this protein in 1 mu s, 1 ms, and 1 s? Assume that this protein is an unhydrated, rigid sphere of density 1.35 g cm^-3.
