BIOD 151 FINAL EXAM MODULE 6 WITH APPROVED AND CORRECT ANSWERS VERIFIED 100%.

List two organs contained in the abdominal cavity. - CORRECT ANSWER-The abdominal cavity contains the stomach, intestines, spleen and liver a. The purpose of cellular respiration is to produce ADP. (T or F) - CORRECT ANSWER-a. False- (ATP is produced, not ADP) b. Peripheral proteins are found on the outer surface of a cell membrane. (T or F) - CORRECT ANSWER-b. True c. Exocytosis is the process that occurs to bring biomacromolecules inside the cell. (T or F) - CORRECT ANSWER-c. False- (This process is called endocytosis) 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) - CORRECT ANSWER-d. True e. Endocytosis is a passive process. It does not require cellular energy expenditure.(T or F) - CORRECT ANSWER-e. False- (Endocytosis is an active process and requires cellular energy) 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? - CORRECT ANSWER-(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. 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. - CORRECT ANSWER-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. Explain what happens to the soft palate during swallowing. Why? - CORRECT ANSWER-The upward movement of the soft palate prevents food or liquid from entering the nasal passages during swallowing. Air and food pass in which one of the following areas: Trachea, Nasopharynx, Oropharynx, Alveoli - CORRECT ANSWER-Oropharynx Label the following five items from the diagram: - CORRECT ANSWER-Label B- Oral Cavity, Label D- Epiglottis, Label E- Glottis, Label F- Trachea, Label G- Esophagus From widest to narrowest, the branches of the bronchial tree are: - CORRECT ANSWER-Primary bronchi, secondary bronchi, tertiary bronchi, bronchioles Explain why someone who has hypergastrinemia (excessive secretion of gastrin) might develop gastric/stomach ulcers. - CORRECT ANSWER-Gastrin stimulates the secretions of pepsinogens and
