testing Membrane Potential and Action Potentials
Question 1
What causes the rapid change in the resting membrane potential to initiate an action potential?
Question 1 options:
Potassium gates open and potassium rushes into the cell, changing the membrane potential from negative to positive
Sodium gates open and sodium rushes into the cell, changing the membrane potential from negative to positive.
Sodium gates close, allowing potassium into the cell to change the membrane potential from positive to negative.
Potassium gates close, allowing sodium into the cell to change the membrane potential from positive to negative.
Question 2
What is the consequence of leakage of lysosomal enzymes during chemical injury?
Question 2 options:
Enzymatic digestion of the nucleus and nucleolus occurs, halting deoxyribonucleic acid (DNA) synthesis.
The influx of potassium ions into the mitochondria occurs, halting the adenosine triphosphate (ATP) production.
Edema of the Golgi body occurs, preventing the transport of proteins out of the cell.
Shift of calcium out of the plasma membrane occurs, destroying the cytoskeleton.
Question 3
In hypoxic injury, sodium enters the cell and causes swelling because
Question 3 options:
The cell membrane permeability increases for sodium during periods of hypoxia.
Adenosine triphosphate (ATP) is insufficient to maintain the pump that keeps sodium out of the cell.
The lactic acid produced by the hypoxia binds with sodium in the cell.
Sodium cannot be transported to the cell membrane during hypoxia.
Question 4
What mechanisms occur in the liver cells as a result of lipid accumulation?
Question 4 options:
Obstruction of the common bile duct, preventing the flow of bile from the liver to the gallbladder
Increased synthesis of triglycerides from fatty acids and decreased synthesis of apoproteins
Increased binding of lipids with apoproteins to form lipoproteins
Increased conversion of fatty acids to phospholipids
Question 5
Which solution is best to use when cleaning a wound that is healing by 101? During an Immunoglobulin E (IgE)-mediated hypersensitivity reaction, the degranulation of mast cells is a result of which receptor action?
Question 5 options:
Histamine bound to H2
Chemotactic factor binding to the receptor
Epinephrine bound to mast cells
Acetylcholine is bound to mast cells.

Average Score 50-85% |
40-38 points More depth/detail for the background and significance is needed, or the research detail is not clear. No search history information is provided. |
83-76 points Review of relevant theoretical literature is evident, but there is little integration of studies into concepts related to problem. Review is partially focused and organized. Supporting and opposing research are included. Summary of information presented is included. Conclusion may not contain a biblical integration. |
52-49 points Content is somewhat organized, but no structure is apparent. The use of font, color, graphics, effects, etc. is occasionally detracting to the presentation content. Length requirements may not be met. |
