FINAL EXAM BIOD 151 EXAM WITH
CORRECT QUESTIONS AND ANSWERS
2025
List two organs contained in the abdominal cavity. - CORRECT-ANSWERSThe
abdominal cavity contains the stomach, intestines, spleen and liver
List two organs contained in the pelvic cavity. - CORRECT-ANSWERSThe pelvic cavity
contains the bladder, reproductive organs and the rectum
o The purpose of cellular respiration is to produce ADP. (T or F) - CORRECT-
ANSWERSFalse- (ATP is produced, not ADP)
o Peripheral proteins are found on the outer surface of a cell membrane. (T or F) -
CORRECT-ANSWERSTrue
o Exocytosis is the process that occurs to bring biomacromolecules inside the cell.
(T or F) - CORRECT-ANSWERSFalse- (process is endocytosis)
o 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-ANSWERSTrue
o Endocytosis is a passive process. It does not require cellular energy expenditure.
(T or F) - CORRECT-ANSWERSFalse- (Endocytosis is an active process and
requires cellular energy)
o Cellular respiration occurs in the mitochondria. (T or F) - CORRECT-
ANSWERSTrue
, o The purpose of cellular respiration is to produce ATP. (T or F) - CORRECT-
ANSWERSTrue
o Integral proteins are only found on the inner surface of a cell membrane. (T or F)
- CORRECT-ANSWERSFalse- (Peripheral proteins are found on the inner or
outer surface of the cell membrane. Integral proteins span the entire length of the
membrane.)
o Endocytosis is the process that occurs to eject biomacromolecules from the cell.
(T or F) - CORRECT-ANSWERSFalse - Exocytosis
o 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-
ANSWERSFalse- (This process is called receptor-mediated endocytosis or
information transfer)
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-
ANSWERSTay-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.
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-ANSWERSThe 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
