FINAL EXAM BIOD 151 ACCURATE QUESTIONS AND ANSWERS WITH SOLUTIONS 2024 1. List two organs contained in the abdominal cavity. - ANSWER The abdominal cavity contains the stomach, intestines, spleen and liver 1. List two organs contained in the pelvic cavity. - ANSWER The pelvic cavity contains the bladder, reproductive organs and the rectum a. The purpose of cellular respiration is to produce ADP . (T or F) - ANSWER False - (ATP is produced, not ADP) b. Peripheral proteins are found on the outer surface of a cell membrane. (T or F) - ANSWER True c. Exocytosis is the process that occurs to bring biomacromolecules inside the cell. (T or F) - ANSWER False - (process is 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) - ANSWER True e. Endocytosis is a passive process. It does not require cellular energy expenditure. (T or F) - ANSWER False - (Endocytosis is an active process and requires cellular energy) a. Cellular respiration occurs in the mitochondria. (T or F) - ANSWER True b. The purpose of cellular respiration is to produce ATP . (T or F) - ANSWER True c. Integral proteins are only found on the inner surface of a cell membrane. (T or F) - ANSWER False - (Peripheral proteins are found on the inner or outer surface of the cell membrane. Integral proteins span the entire length of the membrane.) d. Endocytosis is the process that occurs to eject biomacromolecules from the cell. (T or F) - ANSWER False - Exocytosis e. Pinocytosis uses a signaling molecule from another cell, binding to the cell membrane to bring about changes within the cell proteins.

What are the symptoms of the disease and why do they occur? - ANSWER Tay -Sachs disease impacts the lysosome of the cell because a digestive enzyme in lacking. This leads to a toxic buildup of toxic lipids in the brain that cannot be broken down. This can lead to disability and death. 4. 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 ce ll? Explain why. - ANSWER The smaller cell would be carrying out respiration at a more active rate because its surface area to volume ration is higher than that of the larger cell. When there is more surface are and less volume the small cell allows metabo lic processes in general to occur faster. 4. Explain at least two differences between Type I and Type II alveolar cells. - ANSWER Type I forms the very thin simple squamous epithelium of the alveoli within the junction of the capillaries; also, Type II produce and secrete pulmonary surfactant whic h is needed throughout the alveolar surface; and, Type II cells can divide to replace damaged Type I cells. 5. Explain what happens to the soft palate during swallowing. Why? - ANSWER The upward movement of the soft palate prevents food or liquid from entering the nasal passages during swallowing. 5. Explain what happens to the epiglottis during swallowing. Why? - ANSWER The trachea is closed by the epiglottis. The epiglottis moves inferiorly, covering the trachea. This is to prevent food or liquid from entering the lungs. 6. Air and food pass in which one of the following areas: Trachea Nasopharynx OropharynxThe benefits of buying summaries with Stuvia:
