Cell Transport Mechanisms and Permeability

Exercise 1 cellular telephone TransportMechanisms and PermeabilityActivity 1 Simulating Dialysis (Simple Diffusion) research laboratory Report Pre-lab Quiz Results You scored 75% by settleing 3 out of 4 questions decently.1. The driving force for diffusion is Your rejoinder c. the membrane transport protein.Correct cause b. the kinetic energy of the molecules in motion.2. In diffusion, molecules moveYou correctly answered a. from high minginess to low concentration.3. Which of the following dialysis membranes has the Brobdingnagianst pore surface? You correctly answered d. 200 MWCO4. Avogadros number is a constant for the number ofYou correctly answered b. molecules. try out Results reckon point PredictQuestion 1 The molecular weight of urea is 60.7. Do you moot urea provide piano through the 20 MWCO membrane? Your answer a. Yes, but very slowly. PredictQuestion 2 Recall that glucose is a monosaccharide, white is a protein with 607 amino group acids, and the add up molecular weight of a hit amino acid is one hundred thirty-five g/mole. Which of the following will be commensu count to spread through the 200 MWCO membrane? Your answer b. oth glucose and albuminStop & ThinkQuestions The contend atomic number 11 chloride didnt diffuse left to right is thatYou correctly answered c. the membrane pore size was in like manner 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 run 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 ar both too large to pass.The rate of diffusion for ureaYour answer c. s faster than that for sodium because urea is a smaller molecule.Correct answer b. is dilatory than that for sodium because urea is a large molecule.Post-lab Quiz ResultsYou have not sinless the Post-lab Quiz.Review Sheet Results Describe two vari equal to(p)s that tinge the rate of diffusion. Your answer the solute and the MWCOWhy do you think the urea was not able to diffuse through the 20 MWCO membrane? How healthful did the results analyse with your prediction? Your answer I was ruin. 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.
