Question 1 Not yet graded / 5 pts List two organs contained in the abdominal cavity. Your Answer: the stomach and the spleen The abdominal cavity contains the stomach, intestines, spleen and liver True or False? a. The purpose of cellular respiration is to produce ADP. (T or F) b. Peripheral proteins are found on the outer surface of a cell membrane. (T or F) Question 2 Not yet graded / 5 pts c. Exocytosis is the process that occurs to bring biomacromolecules inside the cell. (T or F) 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) e. Endocytosis is a passive process. It does not require cellular energy expenditure.(T or F) Your Answer: a. False. ATP b. True c. False d. True e. False a. False- (ATP is produced, not ADP) b. True c. False- (This process is called endocytosis) d. True e. False- (Endocytosis is an active process and requires cellular energy) Note: Essay answers must clearly be in your own words. 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? Your Answer: Tay-Sachs occurs when a digestive enzyme in lysosomes is missing. Since the Question 3 Not yet graded / 5 pts digestive enzyme is missing, toxic lipids build up inside the cell which can lead to mental disability and death. (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. Note: Essay answers must clearly be in your own words. 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
