Cell Death Mechanisms Quiz

What is the mechanism of necrosis?

• Enzymatic or ischemic process

• Genetically programmed cell death

• Active process

• Both physiologic and pathologic

Which process is considered a passive process?

• Apoptosis

• Necrosis

• Both apoptosis and necrosis

• Neither apoptosis nor necrosis

What is the physiologic or pathologic role of apoptosis?

• Invariably pathologic

• Both physiologic and pathologic

• Only physiologic

• Only pathologic

How does cell size change in necrosis?

• Enlarged (swelling)

• Reduced (shrinkage)

• No change

• Varies depending on the cell type

Which type of cell death affects a group of cells?

• Apoptosis

• Necrosis

• Both apoptosis and necrosis

• Neither apoptosis nor necrosis

What happens to the nucleus during apoptosis?

• Pyknosis, karyorrhexis, karyolysis

• Fragmentation into nucleosome-size fragments

• No change

• Complete dissolution

What is the state of the plasma membrane in necrosis?

• Intact; altered structure

• Disrupted

• Intact; may be released in apoptotic bodies

• No change

Which process involves enzymatic digestion and leakage of cellular contents?

• Apoptosis

• Necrosis

• Both apoptosis and necrosis

• Neither apoptosis nor necrosis

Is inflammation present in necrosis?

• Yes

• No

• Sometimes

• Depends on the tissue type

What marker is associated with apoptosis?

• No marker

• Annexin V

• Caspase 3

• Bcl-2
