Explain the difference between intracellular, extracellular and intercellular. c. What is an atom? Ion? Molecule? d. Explain at least five characteristics of life. f. e. What is metabolism? Why is it important? What is meant by water soluble (hydrophilic) and water insoluble (hydrophobic, lipid soluble)? Give some specific examples of solutes that are hydrophilic and hydrophobic. g. What are the four macromolecules? Which are hydrophobic and which hydrophilic? h. What are the building blocks/subunits of each of the four organic macromolecules? i. j. What are the types of carbohydrates? Provide one specific example of each. Compare and contrast amylose, cellulose, and glycogen k. Name several specific examples of each of the four macromolecules. l. Explain several functions of each of the four macromolecules. m. Why is the shape of proteins important/significant? n. Why is DNA important in the cell (at least TWO reasons)? o. What is homeostasis? Explain why it is important. 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?
