SAMPLE EXAM 2, ZOOLOGY 101 Spring 2008 Keep the following in mind in using this exam. These are exam questions from Spring 2007 when Dr. Thoma last taught this material in 101. She did not cover all of the same topics as she is covering this semester and those that she did cover were not necessarily covered with the exact same focus or depth. Therefore, realize that not all topics covered so far in this course are represented on this exam nor are those here represented in ratio indicative of how they were covered this semester. This sample exam is provided to give you an idea of the TYPES of questions Dr. Thoma has asked. Expect 4-5 questions per lecture on the exam. Some questions may combine material from more than one lecture. There will also be 1-2 questions based on the article Taming Vessels to Treat Cancer . An answer key will be provided as a separate document. This exam is ONE TOOL for studying, do NOT use it as your sole means of study. It is not meant to take the place of attending lectures and discussions. ------------------------------------------------------------------------------------------------------------------------------- Use the following choices a-e to answer questions 1-4. Each choice may be used once, more than once, or not at all. Each question is worth 1 point. a. Simple Diffusion d. Active Transport b. Facilitated Diffusion (channel protein) e. Exocytosis c. Facilitated Diffusion (carrier protein) 1. Carbon dioxide produced by cellular respiration moves from your cells into the interstitial fluid (fluid surrounding the cell) and then into the bloodstream. The concentration of CO 2 in active cells is much higher than in the interstitial fluid and can move through membranes without the help of membrane proteins. The movement of CO 2 out of your cells can best be described as ___. 2. V-class pumps move H + ions from the cytosol into lysosomes The movement is against the concentration gradient and required ATP for energy. This type of transport is ____ 3. Mucus is essentially a complex of mucin glycoproteins formed in the endomembrane system. Mucus leaves specific cells lining your digestive and respiratory tract by _____ 4. The monosaccharides glucose and galactose serve as basic fuel molecules for eukaryotic cells. These molecules require a protein, GLUT1, for entry into and exit from cells. GLUT1 transports monosaccharides down a concentration gradient, it does not require energy, and it changes shape during transport. The movement of glucose and galactose into your cells can be described as __ ------------------------------------------------------------------------- 5. The cells lining tubules in your kidney have lots of water moving across the membranes. Water moves in and out of the kidney tubules cells by which process? a. Simple diffusion d. a and c are both correct b. Facilitated diffusion e. a, b, and c are all correct c. Osmosis
