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)

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.

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.
Question 4
Not yet graded / 5 pts

Your Answer:
The smaller cell because as a cell grows larger the ratio of the surface area to volume
decreases. The smaller cell is able carry out respiration faster because relative to the
larger cell it has a larger surface area compared to its volume and can carry out
respiration 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.

Explain what happens to the soft palate during swallowing. Why?
Your Answer:
During swallowing the soft palate moves upward to prevent food and liquid from
entering the nasal passages.
