Sample itemWhich feature best distinguishes apoptosis from necrosis?
Original practice item, not a recalled exam question. Nothing here is recorded.
The answer and the reasoning
C. Apoptosis occurs with little surrounding inflammation
Apoptosis is an organized, energy-dependent process with membrane-bound apoptotic bodies rapidly cleared by phagocytes, so it usually produces little inflammatory reaction compared with necrosis.
Option by option
A. Apoptosis always ruptures cell membranes early
Early membrane rupture is characteristic of necrosis rather than apoptosis.
B. Necrosis requires caspase activation
Caspases are central to apoptosis, not typical uncontrolled necrosis.
C. Apoptosis occurs with little surrounding inflammation (correct)
Correct: orderly clearance in apoptosis limits surrounding inflammation.
D. Necrosis never follows ischemia
Ischemia is a common cause of necrosis.
