Portage BIOD 151 Final Exam 2023
List two organs contained in the abdominal cavity. - answerThe abdominal
cavity contains the stomach, intestines, spleen and liver
a. The purpose of cellular respiration is to produce ADP. (T or F) - answera.
False- (ATP is produced, not ADP)
b. Peripheral proteins are found on the outer surface of a cell membrane. (T or F) -
answerb. True
c. Exocytosis is the process that occurs to bring biomacromolecules inside the
cell. (T or F) - answerc. 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) - answerd. True
e. Endocytosis is a passive process. It does not require cellular energy
expenditure.(T or F) - answere. False- (Endocytosis is an active process and
requires cellular energy)
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(1)Lysosomes (2) buildup of toxic lipids inside the cell (biomacromolecules)
(3) disability and death, In the genetic disease known 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.
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. - answerThe smaller cell. Cells need to remain
relatively small because as a cell expands the amount of surface area
