In Celegans,ced-9 Prevents Apoptosis in a Normal Cell in Which of of the Following

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 signalled 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 caspase activity of ced-3 and ced-4, which are required for the initiation and execution of apoptosis. Ced-9 acts as an anti-apoptotic protein and prevents the activation of downstream effectors by blocking the proteolytic activity of ced-3 and ced-4. This mechanism is crucial for the survival of normal cells in C. elegans.
