Membrane Structure

Part A

What is the function of Structure E?

	structural support of the cell
	detection of environmental change
	transport across the plasma membrane
	stabilization of the phospholipids
	cell-cell communication

Correct

Cholesterol helps to stabilize the structure of the plasma membrane.

Part B

Identify Structure D.

	cholesterol
	glycoprotein
	protein
	phospholipid bilayer of membrane
	extracellular matrix

Correct

Phospholipids can be recognized by the presence of a head and two tails.

Part C

Identify Structure A.

	glycoprotein
	phospholipid
	cholesterol
	protein
	extracellular matrix

Correct

Structure A is composed of both a carbohydrate and a protein.
