Exercise 1: Cell Transport
Mechanisms and Permeability:
Activity 1: Simulating Dialysis (Simple Diffusion) Lab Report Pre-lab Quiz Results You scored 75% by correspondent 3 out of 4 questions unexceptionably.
1. The driving sinew for clearance is Your tally : c. the membrane rapture protein.
Correct tally: b. the kinetic courage of the monads in agitation.
2. In clearance, monads move
You unexceptionably tallyed: a. from noble energy to low energy.
3. Which of the forthcoming dialysis membranes has the bulkyst pore greatness? You unexceptionably tallyed: d. 200 MWCO
4. Avogadro's calculate is a uniform for the calculate of
You unexceptionably tallyed: b. monads.
Experiment Results Predict Question: Predict
Question 1: The molecular burden of urea is 60.
7. Do you purpose urea succeed discursive through the 20 MWCO membrane? Your tally : a. Yes, but very sloth. Predict
Question 2: Recall that glucose is a monosaccharide, albumin is a protein delay 607 amino pointeds, and the medium molecular burden of a unmarried amino pointed is 135 g/mole. Which of the forthcoming succeed be effectual to discursive through the 200 MWCO membrane? Your tally : b. oth glucose and albumin
Stop & Think
Questions: The infer sodium chloride didn't discursive left to fit is that
You unexceptionably tallyed: c. the membrane pore greatness was too slight. Glucose is a six-carbon sugar. Albumin is a protein delay 607 amino pointeds. The medium molecular burden of a unmarried amino pointed is 135 g/mole. Tnear is no infer to run these solutes at the 20 MWCO owing
Your tally : b. glucose is a protein and hence too bulky to ignoring. Correct tally: d. glucose and albumin are twain too bulky to ignoring.
The scold of clearance for urea
Your tally : c. s faster than that for sodium owing urea is a slighter monad.
Correct tally: b. is slower than that for sodium owing urea is a bulkyr monad.

Review Sheet Results
Describe two variables that interest the scold of clearance. Your tally: the solute and the MWCO
Why do you purpose the urea was not effectual to discursive through the 20 MWCO membrane? How courteous did the results assimilate delay your vaticination? Your tally: I was wickedness. The urea was too bulky to discursive through the 20 MWCO
Describe the results of the attempts to discursive glucose and albumin through the 200 MWCO membrane. How courteous did the results assimilate delay your vaticination? Your tally: I was wickedness near as courteous. Only the glucose was effectual to discursive.
Put the forthcoming in enjoin from slightest to bulkyst molecular burden: glucose, sodium chloride, albumin, and urea. Your tally: sodium chloride, urea, glucose and albumin.
