Question

Which organelle serves an important role in apoptosis in animals by releasing molecules to trigger cell death?

A. Nucleus
B. Mitochondrion
C. Endoplasmic reticulum
D. Golgi apparatus.

Answer 1

The mitochondrion serves an important role in apoptosis by releasing molecules to trigger cell death.

Step-by-step explanation:

The organelle that serves an important role in apoptosis in animals by releasing molecules to trigger cell death is the mitochondrion.

In apoptosis, the mitochondrion releases a protein called cytochrome C into the cytoplasm, which initiates molecular events leading to cell death.

This process is controlled and prevents the release of potentially damaging molecules from inside the cell.
