KROK 1 2021 – Question 47 · KROK (Medicine) · Pathophysiology
In reperfusion syndrome, the processes of free radical oxidation activate, resulting in damage to cell membranes and disturbance of specific cell functions. These changes are associated with excessive accumulation of the following ions in the cytoplasm:
- A. Chlorine ions
- B. Potassium ions
- C. Sodium ions
- D. Magnesium ions
- E. Calcium ions
Hint
Reperfusion damages membranes and ion pumps, so think about which ion, normally kept extremely low in the cytosol, floods in and activates destructive enzymes.
The answer, the explanation and a note on every option are available once you log in. The account is free: topic tests, a mock exam, mistake review and statistics.
