Choose the best response to the question with the information provided. 1. In your own words, discuss Tay-Sachs disease. What organelle within the cell is impacted? What are the symptoms of the disease and why do they occur? (1)Lysosomes (2) buildup of toxic lipids inside the cell (biomacromolecules) (3) disability and death In the genetic disease known as Tay-Sachs, one of the normally present digestive enzymes inside lysosomes is lacking. Thus, a toxic lipid in the brain cells cannot be broken down. The resulting buildup of lipids in these cells can cause intellectual disability and death. 2. You are observing two cells under the microscope. They are the same type of eukaryotic cell but one appears much larger. Based on appearance alone, which one would you expect to be carrying out respiration at a more active rate, the larger or smaller cell? Explain why. The smaller cell. Cells need to remain relatively small because as a cell expands the amount of surface area relative to the volume of the cell decreases. The smaller cell is more active because relative to its volume, its surface area is larger than a bigger cell. With a larger surface area (relative to its volume) this allows the metabolic processes to occur faster. Module 2 Note: Essay answers must clearly be in your own words.

Make up roughly 95% of alveolar epithelial cells. b. Type II produce and secrete pulmonary surfactant which is needed throughout the alveolar surface to keep the alveoli open. In addition, Type II cells can divide to replace damaged Type I cells. Make up roughly 5% of alveolar epithelial cells. Answer the following five true or false questions: 1.

To receive full credit you must show your work. 110 mmHG 1atm= 760 mmHg 300 mmHg + 350 mmHG + X = 760 mmHg OR: 760 - 300-350= 110 mmHG 2. Why would warming air be beneficial to gas exchange? It would expand the air to make it more available for gas exchange. 3. Explain why incomplete ventilation is important for effective gas exchange. Incomplete ventilation helps to maintain a constant temperature within the lungs. The increased temperature allows for greater gas exchange. Answer the following three questions: 1.

Inspiratory capacity would be abnormally low B. Vital capacity would abnormally high C. Total lung capacity would remain the same A. Inspiratory capacity would be abnormally low Vital capacity would decrease because there is a decreased ability to bring in as much air compared to normal values because of muscular weakness. Inspiratory Capacity (IC) = TV+IRV (or) VC-ERV Decreased VC, decreased IC MODULE 3 Note: Essay answers must clearly be in your own words. All multiple choice questions have one answer unless otherwise specified. Choose the best response with the information provided. Answer the following two questions: 1. Explain why a patient with liver disease would have intolerance to fatty foods. The liver produces bile which breaks down fats. If it is not producing bile (or less bile), fats will not be broken down effectively. 2. Explain in detail how the stomach contents enter the small intestine. The pyloric sphincter (valve), located at the base of the stomach, relaxes causing a small quantity of chyme to pass through the opening into the first part of the small intestine. This initiates a reflex that causes the muscles of the sphincter to contract and close the opening temporarily. Then the sphincter relaxes again and allows more chyme to enter. Look carefully at the diagram below. Label the following 5 organs of the digestive system. To receive credit for the intestines you must label the specific region. 3: Stomach 4: Gallbladder 7: Jejunum (not sm
