problems with vision or hearing• Because certain diseases, such as , involve a breakdown in normal apoptosis, mitochondria are thought to play a role in the disease.
21| Cells with a high demand for energy tend to have greater numbers of mitochondria | Some of the major regions include the: Outer membrane: Small molecules can pass freely through the outer membrane |

| Other roles for calcium in the cell include regulating cellular metabolism, , and | For instance, releasing calcium back into a cell can initiate the release of a neurotransmitter from a nerve cell or hormones from endocrine cells |
Mitochondria release cytochrome C, which activates caspase, one of the chief enzymes involved in destroying cells during apoptosis.
