Experiment Results Predict Questions Stop & Think Questions Molecules need a carrier protein to help them move across a membrane because You correctly answered: they are lipid insoluble or they are too large. 1 Which of the following is true of facilitated diffusion? You correctly answered: Movement is passive and down a concentration gradient. 2 Examples of solutes that might require facilitated diffusion include You correctly answered: all of the above. 3 Which of the following would not affect the rate of facilitated diffusion? You correctly answered: the amount of intracellular ATP. 4 Predict Question 1: What effect do you think increasing the number of protein carriers will have on the glucose transport rate? Your answer: The glucose transport rate will increase. 1 Predict Question 2: What effect do you think adding NaCl will have on the glucose transport rate? Your answer: The glucose transport rate will decrease. 2+- What happened to the glucose transport rate when the glucose concentration was increased from 2 mM to 8 mM? You correctly answered: The glucose transport rate increased. 1 What effect do you think increasing the NaCl concentration will have quizlet?When the NaCl concentration increase from 5 to 10, the pressure increased from 170 to 340. The pressure increased because water diffuses to a higher concentration gradient, so the pressure will increase. Explain the effect that increasing the Na+ Cl- concentration had on osmotic pressure and why it has this effect.
What effect will sodium chloride have on glucose transport rate?Your answer: The glucose transport rate will increase.
What increases the rate of facilitated diffusion of glucose?Answer and Explanation: The diffusion of glucose is a process that takes place in the body. It is facilitated by the movement of molecules from one point to another. The diffusion rate can be increased by increasing the number of molecules or surface area.
What happens to the rate of facilitated diffusion when the number of carrier proteins increases?Carrier proteins increase the rate of diffusion by allowing more solute to enter the cell. Facilitated diffusion, however, approaches a maximum rate as the carrier proteins become saturated with solute.
