B. Write AGREE if the statement speaks of the function of the cell membrane and DISAGREE if it is NOT. Write your answer in the space provided for 1. Separates the contents of the cell from its outside environment and it regulates what enters and exits the cell 2. Plays a vital role in protecting the integrity of the interior of the cell by allowing only selected substance: into the cell and keeping other substances out. 3. Serves as a base of attachment for the cytoskeleton in some organisms and the cell wall in others. 4. Supports the cell and it helps in maintaining the shape of the cell. 5. Monitor and maintain the cell's chemical climate and assist in the transfer of molecules across the membrane

Adi S.
Which statements accurately describe the structure of the cell membrane? Check all that apply. The cell membrane is a double layer of phosphate molecules and lipids. The cell membrane has protein channels that are partly inside and partly outside the cell. The cell membrane's protein channels only let certain molecules pass through.
The cell membrane is composed of a phospholipid bilayer containing proteins and carbohydrates. Choose ALL of the statements that accurately reflect the structure and its function. 1. Membrane proteins may be enzymes to catalyze metabolic reactions within the cell. 2. Membrane proteins may contain cholesterol to serve as identification tags for other cells. 3. Channel proteins allow a specific molecule to cross the cell membrane that is unable to cross the phospholipid bilayer unassisted. 4. Receptor proteins bind to ligands, initiated cell signaling pathways. 5. Molecules that are large or nonpolar must use membrane proteins for transport
