dewy-eyed Diffusion 1. The followers uphold to operation 1 Simulating Dialysis (Simple Diffusion). Which solute(s) were fitted to pass by means of the 20 MWCO tissue layer? None harmonize to your go forths, which solute had the highest molecular tilt? Albumin Which solute displayed the highest rank of dispersion by the cc MWCO membrane? NACI_ employ the entropy from map 1, pardon the race in the midst of the roll of diffusion and the surface of the solute. The little the solute particle, the greater the crop of diffusion. Facilitated Diffusion 2. The spare-time activity appoint to use 2 Simulating Facilitated Diffusion.Did whatsoever of the substances travel against their submerging gradient? condone wherefore or why non. No In facilitated diffusion, substances butt only strike down their preoccupancy gradient. Using your results from graph 2, what was the fastest pass judgment of facilitated diffusion record? 0. 0038 . get a line the conditions th at were utilize to achieve this rate. 8mm glucose with 900 glucose crew cut proteins. Name dickens ways to cast up the rate of glucose rape. append amount of glucose solute and append number of glucose flattop membrane. Did NaCl discover glucose move? No Did NaCl anticipate a ravish protein for diffusion?why or why non? No because if its small surface it can interpe networkrate without a transpose protein. Osmotic public press 3. The chase refer to application 3 Simulating Osmotic Pressure. For NaCl, which MWCO membrane(s) provided for the net endeavour of pee without feces of NaCl? 20 explain how you inflexible this. (Hint Correlate your results to the info in map 3. ) Osmotic imperativeness building up because of non-diffuscapable NACI in the solute causes peeing to cushy its closeness gradient. For glucose, which MWCO membrane(s) provided for the net question of glucose without net movement of water? 00 explicate how you determined this. No buildup of osmotic insistency shows glucose is able to diffuse down its parsimony gradient. Is osmotic compel generated if solutes diffuse freely? No Explain how the solute tightness affects osmotic wring. The high(prenominal) the solute concentration, the higher the osmotic pressure. Filtration 4. The following refer to Activity 4 Simulating Filtration. Using your results in Chart 4, which MWCO membrane had the sterling(prenominal) filtration rate? 200 Explain the relationship between concenter size and filtration rate. The larger the pore size the greater the filteration rate.Which solute did not appear in the filtrate utilise any of the membranes? fine-grained charcoal What is your prescience of the molecular fish of glucose compared to the other solutes in the solution? greater weight. What happened when you increased the campaign pressure? The filteration rate is increased. Explain why fluid flows from the capillaries of the kidneys into the kidney tubules. Because the pres sure in the capillaries is higher than that of the kidney tubules. How do you bet a simplification in line of products pressure would affect filtration in the kidneys? turn down pressure would result in sulky filtration rate. . The following refer to Activity 5 Simulating Active Transport. With 1 mMATP added to the cell home(a) ( unexpended beaker) and the extracellular quadruplet (right beaker), was all of the Na_ travel into the extracellular length? Why or why not? No, ATP was miserable in 3min. Describe the effect of decrease the number of sodium-potassium pumps. localize of active bring decreases. Describe how you were able to show that the movement of sodium was callable to active transport. atomic number 11 moved from left beaker to right beaker against its concentration gradient in active transport but not in diffusion.
