Objective 5A: Membrane structure and Function (5.1-5.5)

5.1.1 Explain how the chemical properties of phospholipids creates a cell membrane that is a bilayer.

5.1.2 Differentiate between integral and peripheral proteins. 

5.1.3 Describe the role membrane carbohydrates play in cell-cell recognition.

5.1.4 Describe the role of the Endoplasmic Reticulum (ER) and Golgi Apparatus in membrane synthesis.

5.2.1 Identify the types of molecules that can and cannot pass through the cell membrane. List examples.

5.2.2 Water can diffuse through the plasma membrane slowly even though it’s polar because it’s so small. What do some cell membranes have that help water move into or out of a cell more quickly?

5.3.1 Describe the process by which molecules move from one area to another during passive transport.

5.3.2 Define osmosis.

5.3.3 Distinguish between hypertonic, hypotonic, and isotonic solutions. 

5.3.4 Model to show a cell in a solution that is in a hypertonic, hypotonic, and isotonic solution compared to the cell. Be sure to indicate the solute concentration (use dots to represent concentration) in both the cell and the solution outside of the cell to make your point. Use arrows to show the flow of water and label what state of the cell to differentiate between animal and plant cells.

5.3.5 Describe the type of molecules that require a protein to diffuse into a cell through facilitated diffusion.

5.4.1 List two main differences between facilitated diffusion and active transport.

5.5.1 Define exocytosis, endocytosis.
