physioex exercise 1 cell transport mechanisms and permeability: activity 3 stimulating osmotic pressure
it is a type of diffusion
which is true about osmosis?
the cells shrink
which occurs when a hypertonic solution is added to cells?
sodium is able to diffuse thru the pores
1. why do you think there is no pressure change w glucose on both sides?
there is no net movement of water because the solute concentrations are the same
2. why do you think there is no pressure change w glucose on right and albumin on left?
double
If you double the concentration of a nondiffusible solute that is on one side of a membrane, the osmotic pressure will
20 MWCO
Which membrane did not allow Na+ Cl- to pass through?
hypotonic solution
the net movement of water would be into the cell in a
the concentration of non diffusing solutes
the variable that affects osmotic pressure is
toward solutes
water diffuses....
pressure above the left beaker
what do you think will be the pressure result of the current experimental conditions?
increased osmotic pressure
what effect do you think increasing the Na+Cl- concentration will have?
equilibrium is reached
when a solute is able to diffuse thru a membrane,
