Plasma Membrane & Transport Test Review

What is structure A?

The plasma membrane is selectively permeable. What does that mean?

• Molecules have to move from high concentration to low concentration

• Proteins are embedded in the plasma membrane

• Some molecules can pass through the membrane when others can not.

• Proteins and phospholipids can move around within the membrane

What structure is the fatty acid tail of the phospholipid?

Solute concentration is equal inside and outside the cell.

• Hypertonic

• Hypotonic

• Isotonic
