Final Exam BIOD 151 Exam Test Questions
with Correct Answers.
1. List two organs contained in the abdominal cavity. - Correct Answer-The abdominal
cavity contains the stomach, intestines, spleen and liver
2. List two organs contained in the pelvic cavity. - Correct Answer-The pelvic cavity
contains the bladder, reproductive organs and the rectum
a. The purpose of cellular respiration is to produce ADP. (T or F) - Correct Answer-False-
(ATP is produced, not ADP)
b. Peripheral proteins are found on the outer surface of a cell membrane. (T or F) - Correct
Answer-True
c. Exocytosis is the process that occurs to bring biomacromolecules inside the cell. (T or
F) - Correct Answer-False- (process is 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
Answer-True
e. Endocytosis is a passive process. It does not require cellular energy expenditure. (T or
F) - Correct Answer-False- (Endocytosis is an active process and requires cellular
energy)
a. Cellular respiration occurs in the mitochondria. (T or F) - Correct Answer-True
b. The purpose of cellular respiration is to produce ATP. (T or F) - Correct Answer-True
c. Integral proteins are only found on the inner surface of a cell membrane. (T or F) -
Correct Answer-False- (Peripheral proteins are found on the inner or outer surface of the
cell membrane. Integral proteins span the entire length of the membrane.)
, d. Endocytosis is the process that occurs to eject biomacromolecules from the cell. (T or
F) - Correct Answer-False - Exocytosis
e. Pinocytosis uses a signaling molecule from another cell, binding to the cell membrane
to bring about changes within the cell proteins. (T or F) - Correct Answer-False- (This
process is called receptor-mediated endocytosis or information transfer)
3. 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
Answer-Tay-Sachs disease impacts the lysosome of the cell because a digestive enzyme
in lacking. This leads to a toxic buildup of toxic lipids in the brain that cannot be broken
down. This can lead to disability and death.
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. - Correct Answer-The smaller cell would be carrying out respiration at a
more active rate because its surface area to volume ration is higher than that of the larger
cell. When there is more surface are and less volume the small cell allows metabolic
processes in general to occur faster.
4. Explain at least two differences between Type I and Type II alveolar cells. - Correct
Answer-Type I forms the very thin simple squamous epithelium of the alveoli within the
junction of the capillaries; also, Type II produce and secrete pulmonary surfactant which is
needed throughout the alveolar surface; and, Type II cells can divide to replace damaged
Type I cells.
5. Explain what happens to the soft palate during swallowing. Why? - Correct Answer-The
upward movement of the soft palate prevents food or liquid from entering the nasal
passages during swallowing.
5. Explain what happens to the epiglottis during swallowing. Why? - Correct Answer-The
trachea is closed by the epiglottis. The epiglottis moves inferiorly, covering the trachea.
This is to prevent food or liquid from entering the lungs.
6. Air and food pass in which one of the following areas:
Trachea
Nasopharynx
with Correct Answers.
