List two organs contained in the abdominal cavity.
The abdominal cavity contains the stomach, intestines, spleen and liver
True or false: The purpose of cellular respiration is to produce ADP
a. False
True or False: Peripheral proteins are found on the outer surface of a cell membrane
True
True or False: Exocytosis is the process that occurs to bring biomacromolecules inside the cell.
False
True or False: Receptor mediated endocytosis uses a signaling molecule from another cell, binding to the cell
membrane to bring about changes within the cell proteins.
True
, True or False: Endocytosis is a passive process. It does not require cellular energy expenditure.
False
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?
Tay-Sachs disease impacts the lysosome of the cell because a digestive enzyme is lacking. This leads to toxic
lipid build-up in the brain that cannot be broken down. This can lead to 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 expands the amount of surface area
relative to the volume of the cell decreases. The smaller cell is more active because relative to its volume, its
surface area is larger than a bigger cell. With a larger surface area (relative to its volume) this allows the
metabolic processes to occur faster.
