Cell Transport Systems and Permeability: Activity two: Simulated Facilitated Diffusion Lab Report Pre-lab Quiz Benefits You obtained 100% by simply answering 4 out of 4 concerns correctly. 1 ) Molecules desire a carrier protein to help them push across a membrane mainly because You properly answered: m.
they are lipid insoluble or perhaps they are too large. 2 . Which usually of the pursuing is true of caused diffusion? You correctly solved: c. Motion is passive and down a concentration lean. 3.
Examples of solutes that might require facilitated diffusion include You correctly answered: deb. all of the previously mentioned. Which with the following will not affect the price of caused diffusion? You correctly solved: a. how much intracellular ATP 08/30/12 webpage 1 Experiment Results Predict Question: Foresee Question 1: What effect do you think increasing the number of necessary protein carriers will have on the glucose transport charge? Your solution: a. The glucose transport rate is going to decrease.
To get facilitated konzentrationsausgleich, increasing the concentration of glucose using one side from the membrane is the same as You properly answered: n.
making the attentiveness gradient steeper 3. When all of the membrane carriers will be engaged, or perhaps busy, we all say they are You correctly responded: a. condensed. Na+ Cl- had simply no effect on sugar transport mainly because You correctly answered: w. odium is not required intended for glucose transfer in the simulation. 08/30/12 site 3 Assessment Sheet Results 1 . Describe one way by which facilitated durchmischung is the same as basic diffusion and one way by which it is totally different from simple konzentrationsausgleich. Your answer: Simple diffussion moves molecules from a location of higher attention to lower without an input of one’s. facilitated comes after the same secret but uses protein transporter molecules to permit substance which have been fat solubles to diffuse through the cell membrane.
The larger value received when even more glucose companies were present corresponds to a rise in the rate of glucose transfer. Explain so why the rate improved. How very well did the results compare with your prediction? Your solution: My conjecture was incorrect the glucose transport level would maximize 3. Explain your conjecture for the effect Na+ Cl- might have on glucose transport. In other words, clarify why you picked the option that you do. How very well did the results match up against your prediction? Your solution: The rate ought to stay ther same 08/30/12 page four
