p. What is negative feedback? q. What is positive feedback?
r. When would positive feedback be important? What are the different components of a negative feedback loop? Explain what each component does. Provide at least 2 specific examples of homeostatic regulation in humans. Include the receptor, integrator and effector for your example. Describe human thermoregulation. s.
t. u. What is vasoconstriction and vasodilation? w. Define isotonic, hypotonic and hypertonic.
Why? a. How is it important in thermoregulation? v. Explain how the body uses insulin and glucagon to regulate blood glucose levels. Where are insulin and glucagon produced? What happens to cells that are placed in each type of solution? Know what the different parts of the cell do (from your posters). Plasma Membrane Review Questions b. c.
d. e. f. g. h. What are the four types of membrane transport proteins? How does each work? Be able to sketch a general schematic of a cell membrane include each part as discussed in class and the function of each component. What are the two major functions of the cell membrane? Be able to describe the functions of the various components of the cell membrane (lipids, proteins, and carbohydrates). What is unique about phospholipids? Briefly describe the different mechanisms (simple diffusion, facilitated diffusion, active transport) by which solutes can cross the membrane. Provide examples of specific substances that cross the membrane by each of the methods discussed. i.
j. How do solid or large particles get through membranes? Compare and contrast the different methods of membrane transport simple diffusion, facilitated diffusion, active transport, and vesicular transport. k. What is the difference between endocytosis and exocytosis? l. Define osmosis. m. What is the sodium-potassium pump? What does it do? n.
o. What ions discussed in class are high on the outside vs. the inside of the cell? What functions do proteins perform in the cell membrane? p. q. the cell?) Unit One Review Questions 2 What are receptors? What are ligands? What jobs do receptor proteins carry out (i.e., how do receptors transmit information into and within 1. What is histology? 2. What is the difference between a tissue and a cell? What about tissues vs. organs? 3. What is the basement membrane/ground substance/extracellular matrix? Why is it important?

How are the different types of epithelial tissues characterized (named)? What are the shapes of the different types of epithelial cells? What are the different types of intercellular junctions? What does each do? What are the two major classes of glands and explain the functions of each? Provide examples of each type. What are some examples of glandular secretions? What are the different types of connective tissues characterized? Where would you expect to find these different connective tissues? Why? What are the different fibrous proteins found in connective tissue? What is the difference between blasts and cytes? What are tissue membranes? What are the four different types of tissue membranes? Where would you expect to find these different membranes? Why? What are the three different types of muscles? What are their different locations and functions?
