EXAM - PORTAGE LEARNING
Question 1
Not yet graded / 5 pts
List two organs contained in the abdominal cavity.
Your Answer:
the stomach and the spleen
The abdominal cavity contains the stomach, intestines, spleen and liver
Question 2
Not yet graded / 5 pts
True or False?
a. The purpose of cellular respiration is to produce ADP. (T or F)
b. Peripheral proteins are found on the outer surface of a cell membrane. (T or F)
c. Exocytosis is the process that occurs to bring biomacromolecules inside the cell. (T or
F)
,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)
e. Endocytosis is a passive process. It does not require cellular energy expenditure.(T or
F)
Your Answer:
a. False. ATP
b. True
c. False
d. True
e. False
a. False- (ATP is produced, not ADP)
b. True
c. False- (This process is called endocytosis)
d. True
e. False- (Endocytosis is an active process and requires cellular energy)
, Question 3
Not yet graded / 5 pts
Note: Essay answers must clearly be in your own words.
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?
Your Answer:
Tay-Sachs occurs when a digestive enzyme in lysosomes is missing. Since the digestive
enzyme is missing, toxic lipids build up inside the cell which can lead to mental disability
and death.
(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.
