Andrewsbio Cell Transport

Front 1

Lipid Bi-layer

Back 1

A double layer of phospholipids that makes up the cell membrane.

Front 2

Concentration

Back 2

The relative amount of solute dissolved in a solution.

Front 3

Diffusion

Back 3

The movement of molecules from an area of high concentration to an area of low concentration. Does not required energy input.

Front 4

Selective Permeability

Back 4

When something only allows certain thing to pass through it.

Front 5

Osmosis

Back 5

The movement of WATER molecules through a cell membrane

Front 6

Facilitated Diffusion

Back 6

When molecules move from an area of high concentration to an area of low concentration through protein channels in the cell membrane. Does not require energy input.

Front 7

Active Transport

Back 7

The movement of molecules from an area of low concentration to an area of high concentration through protein channels in the cell membrane. Required energy input.

Front 8

Endocytosis

Back 8

Process that occurs when the cell takes large amounts of material into the cell by folding in the cell membrane.

Front 9

Exocytosis

Back 9

Process that occurs when the cell releases large amounts of material

Front 10

Hypotonic Solution

Back 10

A solution that contains fewer solute molecules than the cytoplasm of the cell.

Front 11

Hypertonic Solution

Back 11

A solution that contains more solute molecules than the cytoplasm of the cell.

Front 12

Isotonic Solution

Back 12

A solution that contains the same amount of solute molecules as the cytoplasm of the cell.

Front 13

ATP

Back 13

The universal energy storage molecule
