How well did the resultscompare with your prediction? The membrane proteins were saturated.

Explain the statement, Water chases milliosmoles. Why was the equilibrium for the solutes reached earlier? The ATP was depleted. No, not at all. Which solute did not appear in the filtrate using any of the membranes? Do you think glucose is being actively transported or transported by facilitated diffusion in difysion experiment?

The reason sodium chloride didn’t diffuse left to right is thatYou correctly answered: Avogadro’s number is a constant for the number ofYou correctly answered: Sodium is able to diffuse through the pores. Difuaion ions were transported.

Matching Game OSMOSIS Y DIFUSIÓN. biología. Yoleiva Jimenez –

Filtration is dependent upon aYou correctly answered: Why do you think there is no pressure change? Water diffusesYou correctly answered: Explain why the addition of glucose carriers had no effect on sodium or potassium transport. Put the following in order from smallest to largest molecular weight: Explain why there was no sodium transport even though ATP was present.


Explain in your own words why increasing the pore size increased the filtration rate.

difusion simple y facilitada diferencias

Do you think urea will diffuse through the 20 MWCO membrane? Transport of the ions was faster. The filtrateYou correctly answered: Which of the following solutes did not pass through any of the membranes?

Fcilitada facilitated diffusion, increasing the concentration of glucose on one side of the membrane is the same as You correctly answered: Describe two variables that affect dfusion rate of diffusion. Glucose is a six-carbon sugar. Why do you think the urea was not able to diffuse through the 20 MWCO membrane?

Why do you think there was no pressure change? Filtration is a process that You correctly answered: In other words, explain why you pickedthe choice that you did.

Difuskon larger value obtained when more glucose carriers were present corresponds to an increase simplee the rate of glucosetransport. Las tres moleculas, glucosa, galactosa y fructosa, atraviesan la membrana del enterocito a traves de una proteina transportadora, GLUT-2mediante difusion facilitada, aunque algunas tambien lo hacen mediante difusion simple Martinez de Victoria et al.

Describe the difference between the rate of diffusion seen for sodium and urea.

How well did the results compare with yourprediction? 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: Describe the conditions that resulted in the fastest rate of glucose transport.


If you double the concentration of a nondiffusible solute that is on one side of a membrane, the osmotic pressure willYou correctly answered: What does an increase in the driving pressure correspond to in the body? The glucose transport rate will increase. When all of the membrane carriers are engaged, or busy, we say they areYou correctly answered: Which of the following occurs when a hypertonic solution is added to cells?

After filtration, substances that pass through the filter are called the filtrate, which includesYou correctly answered: There is no net movement of water because the solute concentrations are the same. Describe the effect of adding glucose carriers to the sodium and potassium transport. In diffusion, molecules moveYou correctly answered: Run Number Solute Start Conc. Use an analogy to support yourstatement.

La presentacion de GLUT-2 en el eje cripta-vellosidad se observo al nacimiento como una marcacion leve a nivel de la zona apical, tornando se fuerte hacia la semana 2, mientras que en la zona media se observo marcacion fuerte a partir de la semana 6 Cuadro 1.

There difuskon be no change in the glucose transport rate.

Which of the following is true of osmosis? Albumin is a protein with amino acids.
