Cell Transport Mechanisms and Permeability

Exercise 1 Cell TransportMechanisms and Permeability action at law 1 Simulating Dialysis (Simple Diffusion) Lab Report Pre-lab Quiz Results You scored 75% by answering 3 out of 4 questions correctly.1. The driving force for diffusion is Your answer c. the tissue layer transport protein.Correct answer b. the kinetic susceptibility of the molecules in motion.2. In diffusion, molecules moveYou correctly answered a. from high concentration to low concentration.3. Which of the following dialysis membranes has the largest pore sizing? You correctly answered d. 200 MWCO4. Avogadros number is a constant for the number ofYou correctly answered b. molecules.Experiment Results Predict chief PredictQuestion 1 The molecular saddle of urea is 60.7. Do you think urea pull up stakes diffuse finished the 20 MWCO membrane? Your answer a. Yes, but very slowly. PredictQuestion 2 Recall that glucose is a monosaccharide, egg white is a protein with 607 amino acids, and the average molecular fish of a superstar amino acid is 135 g/mole. Which of the following will be able to diffuse finished the 200 MWCO membrane? Your answer b. oth glucose and albuminStop & ThinkQuestions The reason sodium chloride didnt diffuse left to right is thatYou correctly answered c. the membrane pore size was too small. Glucose is a six-carbon sugar. Albumin is a protein with 607 amino acids. The average molecular weight of a single amino acid is 135 g/mole. There is no reason to kick the bucket these solutes at the 20 MWCO becauseYour answer b. glucose is a protein and therefore too large to pass. Correct answer d. glucose and albumin are both too large to pass.The commit of diffusion for ureaYour answer c. s blistering than that for sodium because urea is a smaller molecule.Correct answer b. is slower than that for sodium because urea is a larger molecule.Post-lab Quiz ResultsYou have not completed the Post-lab Quiz.Review Sheet ResultsDescribe two variables that affect the rate of diffu sion. Your answer the solute and the MWCOWhy do you think the urea was not able to diffuse through the 20 MWCO membrane? How well did the results compare with your prediction? Your answer I was wrong. The urea was too large to diffuse through the 20 MWCODescribe the results of the attempts to diffuse glucose and albumin through the 200 MWCO membrane. How well did the results compare with your prediction? Your answer I was wrong here as well. Only the glucose was able to diffuse.Put the following in order from smallest to largest molecular weight glucose, sodium chloride, albumin, and urea. Your answer sodium chloride, urea, glucose and albumin.
