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