Which of the following are involved in cell injury due to ischemia? Select ALL that apply.
A. Na+/K+ membrane pumps will fail
B. Na+ concentration rises outside of the cell.
C. anaerobic metabolism results in elevated intracellular pH.
D. ATP production via aerobic metabolism ceases.
E. lysosomes rupture, speeding cellular destruction
F. the cell swells if intracellular osmotic pressure rises.
G. None of the above

Solution
The option that takes place due to ischema are:
A. Na+/K+ membrane pumps will fail
D. ATP production via aerobic metabolism ceases.
E. Lysosomes rupture, speeding cellular destruction.
F. The cell swells if intracellular osmotic pressure rises. Oxidative stress and tissue damage takes place.
Option C is wrong. Na+/K+ pumps expels H+ ions, as a result pH falls below 6.
Option B is wrong. Na+ concentration rises inside the cell.
