How are peripheral and integral proteins different?
How do the non-polar hydrophobic tails/polar hydrophilic heads in a phospholipid play a
role in cell membrane formation?
Describe the structure of the cell membrane and identify the macromolecules present
Relate the permeability of the cell membrane to its structure
Explain the role of proteins in the cell membrane
Explain how polarity, solubility, and size determine whether a substance will pass
through the cell membrane
Know which types of substances can move into a cell by simple diffusion
Know which types of substances require facilitated diffusion to move into a cell
Know which types of substances require ion channels to move into a cell
Passive Transport
□ Distinguish between diffusion, osmosis, and facilitated diffusion
□ Use solute and/or solvent to determine solution concentration
□ Be able to define and correctly use the following terms as they relate to cell
transport: diffusion, osmosis, concentration gradient, equilibrium, solute, solvent,
hypertonic, isotonic, hypotonic
□ Use the terms above to explain and/or predict movement in given situations (what
direction will water move if a cell is surrounded by a specific concentration of solute,
etc.)
□ Interpret diagrams to describe net movement of materials across a membrane
□ Explain the results of the labs in the unit.
Active Transport
□ Explain why active transport is called active
□ Describe the operation of the sodium-potassium pump
□ Describe the process of endocytosis and exocytosis
□ Differentiate between phagocytosis and pinocytosis
