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-F B-T C-F D-T E-F a. False- (ATP is produced, not ADP) b. True c. False- (This process is called endocytosis) d. True e.

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: A-Lysosomes. B-Buildup of toxic lipids inside the cell 3-Disability, may lead to death Tay-Sachs disease is a genetic disease which one the normal digestive enyzymes inside lysosomes is lacking. because of this enyzymes lacking toxic lipid in the brain cannot be broken down. This results in buildup of lipids whic can cause intellectual disability and/or 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. Question 30 5 / 5 pts 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. Your Answer:

Smaller cells. Cells needs to remain small because if they expand the amount of surface area relative to volume will decrease. The smaller cells are more active compare to larger cells because with a larger surface relative to its volume allows metabolic process to occur faster. 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.
