Chapter 12, Problem 4P

Interpretation Introduction

Interpretation:

The diffusion coefficient at if protein in a membrane of 100 KDa has an effective viscosity of 1 poise and the average distance traveled by 100 kDa protein in and needs to be calculated.

Concept introduction:

Diffusion coefficient also called diffusivity is the diffusing quantity from one region to another passing through unit cross-section area per unit time. It is denoted by D.

Where,

K =Stefan Boltzmann constant

T = Absolute temperature

viscosity of the solvent

r = radius of the sphere.
