Molecule A has a partition coefficient of 2 and a molecule B has partition coefficient of 4. Which molecule will move faster across the membrane? Why?
Homework Answers
Molecule B which has partition coefficient of 4 will move faster across the membrane beacuse higher the partition coefficient, the higher the permeability(ease with which molecules cross through membranes) of membrane.
