In C Elegans, Ced-9 Prevents Apoptosis in a Normal Cell in in Which

Question

In C. elegans, ced-9 prevents apoptosis in a normal cell in which of the following ways?
A) It prevents the caspase activity of ced-3 and ced-4.
B) Ced-9 remains inactive until it is signaled by ced-3 and other caspases.
C) Ced-9 cleaves to produce ced-3 and ced-4.
D) Ced-9 enters the nucleus and activates apoptotic genes.
E) Ced-9 prevents blebbing by its action on the cell membrane.

Accepted Answer

Ced-9 prevents apoptosis by inhibiting the activity of the apoptotic caspases ced-3 and ced-4. This inhibition is a key factor in maintaining cell survival in C. elegans.
