Question 2

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)
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)
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)
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

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
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?
The upward movement of the soft palate prevents food or
liquid from entering the nasal passages during swallowing.
