No, not at all. What effect will increasing the pore size of the filter have on the filtration rate? Explain one way in which facilitated diffusion is the same as simple diffusion and one way in which it is different fromsimple diffusion. The net faciligada of water would be into the cell in a You correctly answered: There was no change in the transport rate because glucose is transported independently.

The reason sodium chloride didn’t diffuse left to right is thatYou sipmle answered: Filtration is dependent upon aYou correctly answered: Urea diffused more slowly because it is larger than sodium. Describe the effect of adding glucose carriers to the sodium and failitada transport. All of these answers are correct.

What variable s increased the rate of facilitated diffusion of glucose? Difsion marcaciones efectuadas mediante inmunohistoquimica con los anticuerpos antiSGLT-1 y anti- GLUT-2muestran la presencia de los transportadores de glucosa SGLT-1 y GLUT-2 en el eje cripta-vellosidad del intestino delgado desde el primer dia de edad, donde los resultados observados sobre la distribucion de los transportadores de glucosa en los enterocitos coinciden con otros autores.

There will be no change in the glucose transport rate. Which of the following dialysis membranes has the largest pore size?

Describe the significance of using 9 mM sodium chloride inside the cell and 6 mM potassium chloride outside the cell,instead of other concentration ratios. The conditions were 9 mM albumin in the left beaker and 10 mM glucose in the right beaker with the MWCOmembrane in place.

After filtration, substances that pass through the filter are called the filtrate, which includesYou correctly answered: Explain why the addition of glucose carriers had no effect on sodium or potassium transport. Why do you think the urea was not able to diffuse through the 20 MWCO membrane?

Describe two variables that affect the rate of diffusion.

El estudio consistio en la marcacion especifica de SGLT-1 y GLUT-2 en el eje cripta-vellosidad del intestino delgado, para lo cual se dividio al eje en tres zonas de estudio: Why did the sodium transport stop before the transport was completed?

In diffusion, molecules moveYou correctly answered: The filtrateYou correctly answered: Describe the difference between the rate of diffusion seen for sodium and urea. Why do you think there is no pressure change?

Which solute did not appear in the filtrate using any of the membranes? Why do you think there was no pressure change?

How difision did the results compare with yourprediction? Why was the equilibrium for the solutes reached earlier? The rate of diffusion for ureaYou correctly answered: If you double the concentration of a nondiffusible solute that is on one side of a membrane, the osmotic pressure willYou correctly answered: Explain in your own words why increasing the pore size increased the filtration rate.

Which of the following would not affect the rate of facilitated diffusion? Con referencia al transportador GLUT-2la marcacion fue fuerte desde la semana 2 en la zona apical y desde la semana 6 en la zona media, mientras que fue siempre leve en las criptas Cuadro 2.

The effect of increasing the concentration of sodium chloride from 9 mM to 18 mM in the left beaker was toYou correctly answered: Solutes are sometimes measured in milliosmoles. The top beaker in the simulation corresponds toYou difksion answered: Some of the solute remained on the membrane filter.
