Move across the membrane to the outside of the cell
Stop moving across the membrane.
Move across the membrane in both directions.
Move across the membrane to the inside of the cell.
Only through a lipid bilayer membrane.
From an area of low concentration to an area of high concentration.
Only in liquids.
From an area of high concentration to an area of low concentration.
Breaks down lipids, carbohydrates, and proteins from foods
Stores water, salt, proteins, and carbohydrates
Keeps the cell wall in place
Regulates which materials enter and leave the cell
Into the cell through the channel protein
Into the cell through the phospholipid bilayer
Out of the cell through the channel protein
Out of the cell through the phospholipid bilayer
Dissolving in blood plasma
Sharing electrons with other ions
Combining with ions of similar charges
Passing through a cell’s plasma membrane
The solution is hypertonic to the cell
The solution and the cell have equal concentrations of solutes
The solution is hypotonic to the cell
The solution and the cell have equal concentrations of water
Always remains great inside a membrane
Eventually becomes balanced on both sides of a membrane
Always remains greater on the outside of a membrane
Becomes imbalance on both sides of a membrane
It requires a carrier protein
It moves substances against a concentration gradient
It requires no energy input
It involves a change in the shape of its carrier
