testation moveCell Transport Mechanisms and Permeability Activity 2 Simulated Facilitated Diffusion Lab Report Pre-lab examine Results You scored 100% by answering 4 out of 4 questions correctly. 1. Molecules need a carrier protein to military service them move across a membrane because You correctly answered d. they be lipid insoluble or they are too large. 2. Which of the following is true of facilitated diffusion? You correctly answered c. Movement is passive and down a immersion gradient. 3.Examples of solutes that might require facilitated diffusion include You correctly answered d. all of the above.Which of the following would not affect the mark of facilitated diffusion? You correctly answered a. the amount of intracellular ATP 08/30/12 page 1 Experiment Results Predict Question Predict Question 1 What act do you think increase the enumerate of protein carriers will have on the glucose transport rate? Your answer a. The glucose transport rate will decrease.For f acilitated diffusion, increasing the stringency of glucose on one side of the membrane is the same as You correctly answered b. making the concentration gradient steeper 3. When all of the membrane carriers are engaged, or busy, we say they are You correctly answered a. saturated. Na+ Cl- had no effect on glucose transport because You correctly answered b. odium is not required for glucose transport in the simulation. 08/30/12 page 3 Review Sheet Results 1. Explain one way in which facilitated diffusion is the same as wide diffusion and one way in which it is different from simple diffusion. Your answer Simple diffussion moves molecules from an area of higher concentration to lower without an input of energy. facilitated follows the same rule nevertheless uses protein carrier molecules to allow substance that are fat solubles to diffuse through the cell membrane.The larger cherish obtained when more glucose carriers were present corresponds to an increase in the rate of glucose transport. Explain why the rate increased. How healthful did the results equal with your prediction? Your answer My prediction was wrong the glucose transport rate would increase 3. Explain your prediction for the effect Na+ Cl- might have on glucose transport. In other words, explain why you picked the choice that you did. How well did the results compare with your prediction? Your answer The rate should stay ther same 08/30/12 page 4
