Portage BIOD 151 Final Exam Questions
And Answers Graded A+.
List two organs contained in the abdominal cavity. - correct answer. The abdominal
cavity contains the stomach, intestines, spleen and liver
a. The purpose of cellular respiration is to produce ADP. (T or F) - correct answer. a.
False- (ATP is produced, not ADP)
b. Peripheral proteins are found on the outer surface of a cell membrane. (T or F) -
correct answer. b. True
c. Exocytosis is the process that occurs to bring biomacromolecules inside the cell. (T or
F) - correct answer. 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) - correct
answer. d. True
e. Endocytosis is a passive process. It does not require cellular energy expenditure.(T
or F) - correct answer. e. 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? - correct
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. - correct answer. The smaller cell. Cells need to remain
