BIOD 151 / A & P 1 (Portage Learning) Final
Exam 1, Exams for Biology with solutions
correct
1. List two organs contained in the abdominal cavity. - ✅✅✅The abdominal
cavity contains the stomach, intestines, spleen and liver
a. The purpose of cellular respiration is to produce ADP. (T or F) -
✅✅✅a. False- (ATP is produced, not ADP)
b. Peripheral proteins are found on the outer surface of a cell
membrane. (T or F) - ✅✅✅b. True
c. Exocytosis is the process that occurs to bring biomacromolecules
inside the cell. (T or F) - ✅✅✅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) - ✅✅✅d. True
e. Endocytosis is a passive process. It does not require cellular energy
expenditure.(T or F) - ✅✅✅e. False- (Endocytosis is an active
process and requires cellular energy)
2. 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? - ✅✅✅(1)Lysosomes (2) buildup of toxic lipids inside the cell
(biomacromolecules) (3) disability and death, In the genetic disease known

correct
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.
3. 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.
4. Explain what happens to the soft palate during swallowing. Why? -
✅✅✅The upward movement of the soft palate prevents food or liquid
from entering the nasal passages during swallowing.
5. Air and food pass in which one of the following areas: Trachea,
Nasopharynx, Oropharynx, Alveoli - ✅✅✅Oropharynx
6. Label the following five items from the diagram: - ✅✅✅Label B- Oral
Cavity, Label D- Epiglottis, Label E- Glottis, Label F- Trachea, Label G-
Esophagus
