62. The safe initiation of the intrinsic pathway of programmed cell death (apoptosis) is triggered by the release into the cytosol of the mitochondrial protein

A. ATP synthase subunit A
B. Cytochrome c
✓
C. Succinate dehydrogenase
D. Malate dehydrogenase

📝 Explanation

Mitochondrial outer membrane permeabilization releases Cytochrome c into the cytosol, where it activates the apoptosome and executioner caspases.

📖 Additional Information

  • ATP synthase subunit A
  • Cytochrome c
  • Succinate dehydrogenase
  • Malate dehydrogenase

Mitochondrial outer membrane permeabilization releases Cytochrome c into the cytosol, where it activates the apoptosome and executioner caspases.
