Result of lipid accumulation

Result of lipid accumulation

3. In hypoxic injury, sodium enters the cell and causes swelling because:

a. The cell membrane permeability increases for sodium during periods of hypoxia.
b. ATP is insufficient to maintain the pump that keeps sodium out of the cell.
c. The lactic acid produced by the hypoxia binds with sodium in the cell.
d. Sodium cannot be transported to the cell membrane during hypoxia.

4. What mechanisms occur in the liver cells as a result of lipid accumulation?

a. Accumulation of lipids that obstruct the common bile duct, preventing flow of bile from the liver to the gallbladder
b. Increased synthesis of triglycerides from fatty acids and decreased synthesis of apoproteins
c. Increased binding of lipids with apoproteins to form lipoproteins
d. Increased conversion of fatty acids to phospholipids

5. During an IgE-mediated hypersensitivity reaction, the degranulation of mast cells is a result of which receptor action?

a. Histamine bound to H2
b. Chemotactic factor binding to the receptor
c. Epinephrine bound to mast cells
d. Acetylcholine bound to mast cells
