PORTAGE BIOD 151 FINAL EXAM QUESTIONS WITH CORRECT VERIFIED ANSWERS | 100% PASS (A+ CERTIFIED) 1. The abdominal cavity contains the stomach, intestines, spleen and liver Correct Answer List two organs contained in the abdominal cavity. 2. a. False- (ATP is produced, not ADP) Correct Answer a. The purpose of cellular respiration is to produce ADP. (T or F) 3. b. True Correct Answer b. Peripheral proteins are found on the outer surface of a cell membrane. (T or F) 4. c. False- (This process is called endocytosis) Correct Answer c. Exocytosis is the process that occurs to bring biomacromolecules inside the cell. (T or F) 5. e. False- (Endocytosis is an active process and requires cellular energy) Correct Answer e. Endocytosis is a passive process. It does not require cellular energy expenditure.(T or F) 6. d. True Correct Answer d. Receptor mediated endocytosis uses a signaling molecule from another cell, binding to the cell membrane to bring about changes within the cell proteins. (T or F) 7. 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 Correct Answer 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? 8. 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 Correct Answer 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. 9. The upward movement of the soft palate prevents food or liquid from en- tering the nasal passages during swallowing Correct Answer Explain what happens to the soft palate during swallowing. Why?
