Diffusion through biological membranes Flashcards
1
Q
what is Fick’s law for dual chamber diffusion cell?
A
J=dm/dt= ADC*P / h
2
Q
why is the Ficks law modification for dual chamber diffusion cell not used?
A
not possible to determine D P and h so permeability coefficient is used
3
Q
what is permeability coefficient?
A
Kp = DP/h (cm/s)
4
Q
what is Fick’s law using the permeability coefficient?
A
dm/dt = A x Kp x C
5
Q
what is are the units for area, concentration and rate?
A
area= cm2
concentration= mmolcm-3
rate= mmol s-1
