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.
Explain what happens to the soft palate during swallowing. Why?
The upward movement of the soft palate prevents food or liquid from entering the nasal
passages during swallowing.
Air and food pass in which one of the following areas: Trachea, Nasopharynx,
Oropharynx, Alveoli
Oropharynx
Label the following five items from the diagram:
Label B- Oral Cavity, Label D- Epiglottis, Label E- Glottis, Label F- Trachea, Label G-
Esophagus
