Questions of Diffusion

Which of the following would decrease the rate of facilitated diffusion? decreasing the number of carrier proteins
What happens to facilitated diffusion when the protein carriers become saturated? The maximum rate of transport will occur.
What happened when sodium chloride was added as a solute in the left beaker? There was no change in the transport rate of glucose.
Which of the following statements about carrier proteins is FALSE? They assist in simple diffusion.
Which of the following statements about facilitated diffusion is FALSE? The movement of a given solute usually occurs in both directions (into and out of the cell).
Which of the following is NOT a reason why a solute would require facilitated diffusion? The solute directly requires ATP for its transport.
Which of the following would increase the rate of facilitated diffusion? increasing the steepness of the concentration gradient
