Which image correctly shows the way phospholipids arrange themselves in the cell (plasma) membrane?

• 
• 
• 
• 

The model that describes the current understanding of the cell (plasma) membrane structure is

• fluidity model

• fluid mosaic model

• semi-permeable model

• flexible mixture model

Proteins that make up the cell (plasma) membrane

• are only found on the outer side of the phospholipid bilayer

• are able to provide a passageway for certain substance to pass through the membrane

• are only found on the inner side of the phospholipid bilayer

• are only found in the middle of the phospholipid bilayer

The ability of the cell (plasma) membrane to control what substances can pass through is referred to as

• semi-barrier

• semi-permeable

• fully permeable

• fluid mosaic
