ACTIVITY ONE- Cell Transportation Mechanisms and Permeability: Simulating Dialysis (Simple Diffusion)
1 . Identify two variables that impact the rate of diffusion.
Molecular weight influences the rate of diffusion for the reason that bigger how big the molecule the longer it will take to diffuse. Membrane size is another variable that affects the pace of durchmischung because in the event the membrane's skin pores are little it will take elements longer to diffuse though it than if the skin pores were bigger. Also, membrane layer thickness is known as a variable since the thinner the membrane the quicker the diffusion.
2 . Why do you think the urea had not been able to diffuse through the 20 MWCO membrane layer? How well did the results compare with your conjecture?
Our prediction was that urea was not going to be able to diffuse through the twenty Molecular Fat Cut Off (MWCO) membrane because urea is too big of the molecule to diffuse throughout the 20 MWCO membrane's follicles aren't adequate for the urea to feed. Our conjecture was right, the Urea was struggling to diffuse although such a tiny membrane.
3. Explain the results of the endeavors to diffuse glucose and albumin through the 200 MWCO membrane. How well would the outcomes compare with the prediction?
We all predicted that glucose and albumin will both dissipate very little by little through the two hundred MWCO as they are large molecules. The results were; the glucose diffused throughout the 200 MWCO membrane for a price of 0. 0040 per minute. The albumin was not capable of diffuse throughout the 200 MWCO because it is too big of a molecule to fit through the membrane pore.
5. Put the following in order from smallest to largest molecular weight: blood sugar, sodium chloride, albumin, and urea.
Salt Chloride, Urea, Glucose, and Albumin.
ACTIVITY 2- Cell Transfer Mechanisms and Permeability: Lab-created Facilitated Durchmischung
1 ) Explain a method in which caused diffusion is the same as simple konzentrationsausgleich and one of many ways in which it truly is different from simple diffusion.
Facilitated diffusion is the same as simple durchmischung in that they are both passive and go down (or with) the concentration lean. It is not the same as simple diffusion in that caused diffusion uses a carrier protein to transport this across the membrane.
2 . The bigger value obtained when even more glucose providers were present corresponds to an increase in the rate of glucose transport. Explain why the rate increased. How well did the results compare with your prediction?
The rate of glucose that was transported increased mainly because when the attention of sugar got bigger, so the level of konzentrationsausgleich went up. When we have a higher concentration gradient the speed of diffusion increases, so the more sugar carriers managed to get easier for the sugar to dissipate more quickly though the membrane. All of us predicted the fact that rate of diffusion would be slower due to more elements, but the end result was the contrary, and at enough time we did not know about Fick's Law of diffusion.
3. Explain your prediction for the effect Na+ Cl- may have on glucose transport. Basically, explain why you picked out the choice that you just did. Just how well would the effects compare with the prediction?
We all predicted that the glucose transport rate might increase. All of us predicted this because we all thought that by making use of Na+Cl- it would help the blood sugar molecules diffuse through the membrane layer more quickly than without it. Our effects matched the prediction. The Na+Cl- caused the blood sugar though the membrane layer more quickly.
