When the solutes are evenly distributed throughout a solution, we say the solution has reached _______. |
equilibrium |
|
Which of the following is NOT a passive process? |
vesicular transport |
|
Which of the following does NOT describe the plasma membrane? |
impermeable |
|
Which of the following requires a membrane-bound carrier for transport? |
facilitated diffusion |
|
Which of the following solutes would move the fastest? |
sodium chloride |
|
For solutes that are membrane permeable, which of the following does NOT affect the rate of diffusion? |
the potential energy of the solute and the size of the pore |
|
In this activity, the solutes were transported through the dialysis membrane by _______. |
simple diffusion |
|
Through which membrane(s) would sodium chloride diffuse? |
50 MWCO, 100 MWCO, and 200 MWCO |
|
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 |
|
Simple diffusion and facilitated diffusion both _______. |
move solutes with their concentration gradient |
|
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. |
