1. List two organs contained in the abdominal cavity.: The abdominal cavity
contains the stomach, intestines, spleen and liver
2. True or false: The purpose of cellular respiration is to produce ADP: a. False
3. True or False: Peripheral proteins are found on the outer surface of a cell
membrane: True
4. True or False: Exocytosis is the process that occurs to bring biomacromol-
ecules inside the cell.: False
5. 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.: True
6. True or False: Endocytosis is a passive process. It does not require cellular
energy expenditure.: False
7. 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?: 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.
8. 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.
9. Explain what happens to the soft palate during swallowing. Why?: The up-
ward movement of the soft palate prevents food or liquid from entering the nasal
passages during swallowing.
10. Air and food pass in which one of the following areas: Trachea, Nasophar-
ynx, Oropharynx, Alveoli: Oropharynx
11. Label the following five items from the diagram:: Label B- Oral Cavity, Label
D- Epiglottis, Label E- Glottis, Label F- Trachea, Label G- Esophagus
12. From widest to narrowest, the branches of the bronchial tree are:: Primary
bronchi, secondary bronchi, tertiary bronchi, bronchioles
13. Explain why someone who has hypergastrinemia (excessive secretion of
gastrin) might develop gastric/stomach ulcers.: Gastrin stimulates the secre-
tions of pepsinogens and hydrochloric acid. Excess amounts would lead to erosion
of the stomach lining.
