Question 2

• / 5 pts

True or False?

• The purpose of cellular respiration is to produce ADP. (T or F)
• Peripheral proteins are found on the outer surface of a cell

membrane. (T or F)

• Exocytosis is the process that occurs to bring

biomacromolecules inside the cell. (T or F)

• 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)

• Endocytosis is a passive process. It does not require cellular

energy expenditure.(T or F)

• False- (ATP is produced, not ADP)
• True
• False- (This process is called endocytosis)
• True
• False- (Endocytosis is an active process and requires

cellular energy) 1 / 2

Question 3

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?(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 4

• / 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.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
