Compartmentalization is a major determinant of physiological processes in cells. A. Describe one way in which "compartmentalization" contributes to cell signaling. B. Provide one way in which compartmentalization contributes to cell survival by protecting cells from inappropriate activation of apoptotic programs. C. Describe one signal that triggers "release" or "activation" of a pro-apoptotic protein that is normally maintained in an inactive form (or sequestered from its target)..
