The 'executioner' enzymes that directly carry out the cleavage of proteins during apoptosis are known as:
Show answer and explanation
Correct answer: Caspases
Caspases (Cysteine-Aspartic Acid Proteases) are the central mediators of apoptosis. Executioner caspases, such as Caspase-3 and Caspase-6, cleave structural and regulatory proteins leading to the characteristic morphology of programmed cell death.
