Straightforward Diffusion

1 . The following refer to Activity 1: Simulating Dialysis (Simple Diffusion). Which will solute(s) were able to pass through the 20 MWCO membrane? None of them would

According on your results, which solute acquired the highest molecular weight? Albumin

Which in turn solute exhibited the highest rate of durchmischung through the two hundred MWCO membrane layer? Na+CI

Using the data from Graph 1, describe the relationship between rate of diffusion as well as the size of the solute. The bigger rates of diffusion happened with a more compact weight of solute.

Facilitated Konzentrationsausgleich

installment payments on your The following make reference to Activity 2: Simulating Facilitated Diffusion. Do any of the substances travel against their attention gradient? Make clear why or why not. Zero, because the solutes can only maneuver down the attentiveness gradient within a facilitated konzentrationsausgleich, not up against the concentration lean.

Using your comes from Chart 2, what was the fastest price of caused diffusion recorded? 0. 0039

Identify the conditions that had been used to accomplish this rate. Glucose concentration was 8mm, sugar carriers were 900

Name two ways to increase the rate of glucose transport.

A higher quantity of glucose carriers, or a higher amount of glucose in a solution.

Did NaCl influence glucose transportation?

no

Did NaCl need a transport protein for diffusion? Why or perhaps why not? NaCI is small enough to diffuse down its attention gradient, permitting it to never need a travel protein.

Osmotic Pressure

3. This refer to Activity 3: Simulating Osmotic Pressure. For NaCl, which MWCO membrane(s) provided for the net movements of drinking water without activity of NaCl? 20 MWCO

Make clear how you identified this. (Hint: Correlate the results to your data in Data 3. ) The build up of osmotic pressure occurring from the low diffusible NaCI in the option causes the to dissipate down is actually concentration gradient.

For blood sugar, which MWCO membrane(s) provided for the net motion of blood sugar without net movement of water?

Explain how you determined this.

Can be osmotic pressure generated if solutes dissipate freely?

Explain the way the solute attentiveness affects osmotic pressure.

Filtration

5. The following label Activity 4: Simulating Purification. Using your brings about Chart 4, which MWCO membrane experienced the greatest purification rate? Clarify the relationship among pore size and purification rate.

Which usually solute would not appear in the filtrate applying any of the membranes? What is your prediction of the molecular weight of glucose in comparison to the other solutes in the option? What happened at the time you increased the driving pressure?

Explain so why fluid runs from the capillary vessels of the kidneys into the kidney tubules.

How would you think a decrease in stress would influence filtration inside the kidneys?

5. The following make reference to Activity a few: Simulating Effective Transport. With 1 millimeter ATP included with the cell interior (left beaker) plus the extracellular space (right beaker), was all the Na+ moved into the extracellular space? How come or obtain?

Describe the effect of lowering the number of sodium-potassium pumps. Illustrate how you could actually show that the movement of sodium was due to energetic transport.
