A+.
1. List two organs contained in the abdominal cavity.
ANSWER ✔✔ The abdominal cavity contains the stomach, intestines, spleen, and liver.
2. List two organs contained in the pelvic cavity.
ANSWER ✔✔ The pelvic cavity contains the bladder, reproductive organs, and the rectum.
3. The purpose of cellular respiration is to produce ADP. (T or F)
ANSWER ✔✔ False (ATP is produced, not ADP).
4. Peripheral proteins are found on the outer surface of a cell membrane. (T or F)
ANSWER ✔✔ True.
5. Exocytosis is the process that occurs to bring biomacromolecules inside the cell. (T or F)
ANSWER ✔✔ False (The process is endocytosis).
6. 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)
ANSWER ✔✔ True.
7. Endocytosis is a passive process. It does not require cellular energy expenditure. (T or F)
ANSWER ✔✔ False (Endocytosis is an active process and requires cellular energy).
, 8. Cellular respiration occurs in the mitochondria. (T or F)
ANSWER ✔✔ True.
9. The purpose of cellular respiration is to produce ATP. (T or F)
ANSWER ✔✔ True.
10. Integral proteins are only found on the inner surface of a cell membrane. (T or F)
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).
11. Endocytosis is the process that occurs to eject biomacromolecules from the cell. (T or F)
ANSWER ✔✔ False (Exocytosis is the process for ejection).
12. Pinocytosis uses a signaling molecule from another cell, binding to the cell membrane to
bring about changes within the cell proteins. (T or F)
ANSWER ✔✔ False (This process is called receptor-mediated endocytosis or information
transfer).
13. 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 a toxic buildup of lipids in the brain that cannot be broken down,
resulting in disability and death.
14. 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 would be carrying out respiration at a more active rate because
its surface area to volume ratio is higher. This allows metabolic processes to occur faster in the
smaller cell.
