What variable s increased the rate of facilitated diffusion of glucose?

Farmacocinética

The glucose transport rate increased. En el experimento se uso 9mM de cloruro de sodio dentro de la celula y y 6 mM de cloruro de potasio fuera de la celulaporque esas son las razones de proporcion para que funciones la bomba sodio-potasio, ya que esta expulsa tres iones dede sodio hacia el exterior de la celula por cada dos iones simplr potasio que ingresan a la celula.

There were more pumps for transport. There was no change in the transport rate because glucose is transported independently.

How well did theresults compare with your prediction? The net movement of water would be into the cell in a You correctly answered: Why did the sodium transport stop before the transport was completed? Explain in your own words why increasing the pore size increased the filtration rate.

Put the following in order from smallest to largest molecular weight: Why do you think the urea was not able to diffuse through the 20 MWCO membrane? References in periodicals archive?

Si bien es cierto que GLUT-2 se encuentra en algunos casos desde el nacimiento, su ubicacion es wimple basolateral y no apical, que es la posicion de mayor actividad biologica para GLUT-2 durante esta etapa.

The larger value obtained when more glucose carriers were present corresponds to an increase in the rate of glucosetransport. Sodium is able to diffuse through the pores.

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.

Which solute did not appear in the filtrate using any of the membranes? In other words, explain why you pickedthe choice that you did.

En el presente estudio, se demuestra la presencia de los transportadores de glucosa SGLT-1 y GLUT-2 a nivel basolateral y apical desde el dia del nacimiento en la alpaca. What happened when you increased the amount of ATP dispensed with the same concentration of sodium andpotassium on either side of the membrane?

Correr el Ejercicio N 1: Filtration is a process that You correctly answered: The glucose transport rate will increase. Explain why there was no sodium transport even though ATP was present. When a solute is able to diffuse through a membraneYou correctly answered: Post on Dec 42 views.

Which of the following occurs when a hypertonic solution is added to cells? Which of the following dialysis membranes has the largest pore size? Describe the conditions that resulted in the fastest rate of glucose transport.

The filtration rate will increase. Run Number Solute Start Conc. El GLUT-2 presento una marcacion leve en la zona apical hasta las semana 4 y fuerte desde la semana 5, mientras que en la zona media y cripta fue leve desde la semana sijple Cuadro 3.

Use an analogy to support yourstatement. Movement is passive and down difudion concentration gradient. Transport of the ions was faster.

Explain the statement, Water chases milliosmoles. Why did increasing the pressure increase the filtration rate but not the concentration of solutes? What do you think will be the pressure result of the current experimental conditions? Which of the following is true of osmosis? The conditions were 9 mM albumin in the left beaker and 10 mM glucose in the right beaker with simpe MWCOmembrane in place.

Cell Transport Mechanisms and Permeability: How welldid the results compare with your prediction? The molecular weight of urea is What does an increase in the driving pressure correspond to in the body? The rate of diffusion for ureaYou correctly answered: Orden de moleculas de menor a mayor peso molecular: Permeabilidad y mecanismos de transporte celular: What effect do you think increasing the number of protein carriers will have on the glucose transportrate?

The filtrateYou correctly answered: Describe the effect of adding glucose carriers to the sodium and potassium transport.
