List two organs contained in the abdominal cavity. - Correct
Answers ✅The abdominal cavity contains the stomach,
intestines, spleen and liver
a. The purpose of cellular respiration is to produce ADP. (T or
F) - Correct Answers ✅a. False- (ATP is produced, not ADP)
b. Peripheral proteins are found on the outer surface of a cell
membrane. (T or F) - Correct Answers ✅b. True
c. Exocytosis is the process that occurs to bring
biomacromolecules inside the cell. (T or F) - Correct
Answers ✅c. False- (This process is called endocytosis)
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) - Correct
Answers ✅d. True
e. Endocytosis is a passive process. It does not require
cellular energy expenditure.(T or F) - Correct Answers ✅e.
False- (Endocytosis is an active process and requires cellular
energy)

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? - Correct Answers
✅(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. - Correct Answers
✅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? - Correct Answers ✅The upward movement of the
soft palate prevents food or liquid from entering the nasal
passages during swallowing.
