A. Immune cells trigger an apoptosis pathway that uses only executioner caspases.

B. Immune cells trigger an apoptosis pathway that uses only initiator caspases.

A. Immune cells trigger an apoptosis pathway that uses only executioner caspases.

B. Immune cells trigger an apoptosis pathway that uses only initiator caspases.

C. Apoptosis triggered by immune cells leads to release of cytochrome C from mitochondria.

D. Immune cells activate death receptors in target cells.

Explanation / Answer

During infected cells mitochondria plays a major role in apostosusbas well as nervous where apostosis is done by the release of cytochrome C from the organelle.

Therefore (C) Apoptosis triggered by immune cells leads to release of cytochrome C from mitochondria is the answer
