Question
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.

Hydrolysis .? And what is endocytosis pinocytosis phagocytosis explain with reactions or diagram.
resting state of the protein, the Lys 216 Schiff base has pKa = 9.5 and Asp 85 has pKa = 3.5. When the conformational change occurs, the proton that was on the Schiff base moves to Asp 85. This should tell you that one or both of these two pKas
changed with the conformational change. How does the pKa of Asp 85 compare with the pKa of the Lys 216 Schiff base after the conformational change?
