Portage BIOD 151 Anatomy and
Physiology Final Exam
List two organs contained in the abdominal cavity. - ANSWER The abdominal cavity
contains the stomach, intestines, spleen and liver
True or false: The purpose of cellular respiration is to produce ADP - ANSWER a.
False
True or False: Peripheral proteins are found on the outer surface of a cell membrane
- ANSWER True
True or False: Exocytosis is the process that occurs to bring biomacromolecules
inside the cell. - ANSWER False
True or False: Receptor mediated endocytosis uses a signaling molecule from
another cell, binding to the cell membrane to bring about changes within the cell
proteins. - ANSWER True
True or False: Endocytosis is a passive process. It does not require cellular energy
expenditure. - ANSWER False
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? -
ANSWER Tay-Sachs disease impacts the lysosome of the cell because a digestive
enzyme is lacking. This leads to toxic lipid build-up in the brain that cannot be broken
down. This can lead to 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. - ANSWER 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? - ANSWER The
upward movement of the soft palate prevents food or liquid from entering the nasal
passages during swallowing.
Air and food pass in which one of the following areas: Trachea, Nasopharynx,
Oropharynx, Alveoli - ANSWER Oropharynx
Label the following five items from the diagram: - ANSWER Label B- Oral Cavity,
Label D- Epiglottis, Label E- Glottis, Label F- Trachea, Label G- Esophagus
