|
what is Fick's Law?
|
J = PA (CA -CB)
J - net rate of diffusion (mmol/sec) P - permeability (cm/sec) A - surface area for diffusion (cm^2) CA, CB - concentration A and B (mmol/L) |
|
|
how does Fick's law relate to physiology?
|
quantifies the diffusion of molecules across a membrane
(not accounting for electrical potentials) |
|
|
how does a Na,K-ATPase work?
|
Na binds
ATPase is phosphorylated bound Pi causes conformational change (opens to outside) Na released, K bound Pi is released causing ATPase to open inside the cell K released, Na bound |
|
|
what transporter carries glucose from the intestinal lumen into intestinal epithelial cells?
|
SGLT
|
|
|
how is osmolarity calculated?
|
osmolarity = g x C
g - number of particles per mole in solution (Osm/mol) C - concentration (mol/L) |
