Chapter 50.5, Problem 3SB
Summary Introduction
To review:
The activation state of CED-9 (Cell death abnormality gene 9) plays a crucial role in apoptosis.
Introduction:
Apoptosis is also called programmed cell death. This type of cell death occurs orderly, which involves the cell shrinkage, and nuclear and chromosomal fragmentation leading to cell death. It helps in the removal of cancerous and infected cells from the body.

You've engineered a version of the Bax protein that is functional, but is mislocalized to the plasma membrane rather than the mitochondria. You expect that this will block the intrinsic pathway of apoptosis. When you activate the intrinsic pathway of apoptosis, you are surprised to find that the cells still die. You then do a cell fractionation experiment and verify that Bax is. indeed being sent to the plasma membrane, rather than the mitochondria. In one sentence, what is the most likely hypothesis for what is happening?arrow_forward
