Cell Membrane Structure

Front 1

Plasma membrane

Back 1

Membrane that separates the inside of the cell from the outside.

Front 2

Phospholipid Bilayer

Back 2

The plasma membrane is made up of two layers of phospholipids that are tail to tail. Phospholipids are fats.

Front 3

Cytoplasm

Back 3

The inside of a cell

Front 4

extracellular space

Back 4

space outside and in between each cell

Front 5

membrane protein

Back 5

Protein embedded inside the membrane

Front 6

Channel protein

Back 6

Protein that runs all the way through the plasma membrane. Use for passive transport inside and outside of cell.

Front 7

Carrier protein

Back 7

Protein that runs all the way through the plasma membrane. Allows specific molecules or ions to cross membrane

Front 8

Receptor protein

Back 8

Protein in the plasma membrane that is shaped in a specific way so that a molecule or signal can bind to it.

Front 9

hydrophobic

Back 9

parts of the plasma membrane or phospholipid that do not interact with water

Front 10

hydrophilic

Back 10

parts of the plasma membrane or phospholipid that interact with water

Front 11

cholesterol

Back 11

fatty structures within membrane that allow it to move fluidly

Front 12

semipermeable

Back 12

a membrane or structure that allows some (but not all) molecules or ions to pass through
