Function of Caspase: Protease that executes the death signal by cleaving numerous cellular proteins. Substrate+enzymatic activity: Active-site cysteine cleaves target proteins C-terminal to aspartate residues.

A) Caspase activates cell survival pathways.
B) Caspase cleaves proteins at the N-terminal.
C) Caspase functions in apoptosis by cleaving proteins.
D) Caspase is unrelated to cellular processes.
