MOMP has been referred to as the point of no return for apoptosis, almost always resulting in the completion of the process, and thus, cell death. However, in limited circumstances, apoptosis does not complete. Sometimes, MOMP does not complete, known as incomplete MOMP (iMOMP) or minority MOMP

In minority MOMP, only a few mitochondria of the cell experience MOMP—the result of sublethal stress. 64:, forms pores during MOMP that allow it to accommodate proteins larger than 100 kDa. During MOMP, it takes about five minutes for all mitochondrial membranes within a cell to permeabilize. 57: 53: 249: 28: 244: 168: 139:"Mitochondrial outer membrane permeabilization during apoptosis: The innocent bystander scenario" 220: 160: 116: 210: 202: 150: 106: 111: 94: 215: 190: 238: 61: 60:.
