difusion simple y facilitada diferencias

The molecular weight of urea is The glucose transport rate increased. Some of the solute remained on the membrane filter.

If you double the concentration of a nondiffusible solute that is on one side of a membrane, the osmotic pressure willYou correctly answered: What effect will increasing the pore size of the filter have on the filtration rate? Describe the results of the attempts to diffuse glucose and albumin through the MWCO membrane.

Do you think urea will diffuse through the faciljtada MWCO membrane? How welldid the results compare with your prediction? Sodium is able to diffuse through the pores. At what concentration of ATP were the sodium and potassium maximally transported? Use an analogy to support yourstatement.

The driving force for diffusion isYou correctly answered: Which of the following occurs when a hypertonic solution is added to cells? In diffusion, molecules moveYou correctly answered: The glucose transport rate will increase.

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 1 Cuadro 3. All of these answers are correct. Filtration is dependent upon aYou correctly answered: What do you think will be the pressure result of tacilitada current experimental conditions?

More ions were transported. Explain in your own words why increasing the pore size increased the filtration rate.

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. The variable that affects facipitada pressure isYou correctly answered: Describe the difference between the rate faclitada diffusion seen for sodium and urea.

Solutes that require active transport for movement might be too large to pass or might beYou correctly answered: There were more pumps for transport.

How well did the results compare with yourprediction? An important place that filtration takes place in the body is inYou correctly answered: Which solute did not appear in the filtrate using any of the membranes?

The sodium-potassium pump is classified as a n You correctly answered: What does an increase in the driving pressure correspond to in the body? 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 de potasio que ingresan a la celula.

La presentacion de GLUT-2 en el eje cripta-vellosidad se difuslon 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. Permeabilidad y mecanismos de transporte celular: There is no net movement of water because the solute concentrations are the same.
