1. How do peripheral and integral proteins differ?
2. Describe a transmembrane protein (i.e. characterstics).
3. How is each type of junction suited to the types of tissues each is located in? Give specific examples of tissue types for each type of junction.
4. What determines if a ligand will bind with a receptor protein?
5. Is it possible for more than one type of ligand to bind to a binding site? Explain.
6. Define affinity and describe and differentiate between the 3 types of affinities a binding site can possess.
7. (a) Which two factors most affect the percentage of saturation? (b) Explain the significance of 100% saturation relative to ligand concentration.
8. What effect does ligand concentration have on specificity, affinity, saturation and competition? (note: "what effect" means "increase, decrease, or no effect". For example, does ligand concentration increase or decrease specificity?)
9. Identify the two major ways of controlling protein activity.
10. An enzyme is said to be a catalyst. What does an enzyme do to catalyze reactions?
