What is the function of the phospholipid bilayer in the cell membrane?

• It breaks apart the phospholipids so that things can move freely in the membrane.

• It acts as the basic shape and structure of the cell membrane.

• It chemically identifies passing cells and molecules.

• It acts as a channel to allow certain objects to pass in and out of the cell.

What is the function of a transport protein in the cell membrane?

• It breaks apart the phospholipids so that things can move freely in the membrane.

• It acts as the basic shape and structure of the cell membrane.

• It chemically identifies passing cells and molecules.

• It acts as a channel to allow certain objects to pass in and out of the cell.

Define selectively permeable:

• Capable of changing shape.

• Made only out of the 4 biomolecules.

• Allows all objects to pass through.

• Allowing only certain objects to pass through.

Define active transport:

• Movement of objects in and out of the cell USING ENERGY.

• Movement of objects in and out of the cell WITHOUT USING ENERGY.

• Movement of organic matter in and out of the cell.

• Movement of inorganic matter in and out of the cell.
