Portage BIOD 151 Final Exam
Questions and Answers4
a. The purpose of cellular respiration is to produce ADP. (T or F) - ANSWERS a. False- (ATP is
produced, not ADP)
b. Peripheral proteins are found on the outer surface of a cell membrane. (T or F) - ANSWERS b.
True
c. Exocytosis is the process that occurs to bring biomacromolecules inside the cell. (T or F) -
ANSWERS 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) - ANSWERS d. True
e. Endocytosis is a passive process. It does not require cellular energy expenditure.(T or F) -
ANSWERS 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? - ANSWERS (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.
List two organs contained in the abdominal cavity. - ANSWERS The abdominal cavity contains
the stomach, intestines, spleen and liver
