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.

Question 2 (5 points)
What is a 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.
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.
