1. | Mitochondria contain their own DNA and ribosomes, which allows them to replicate independently within the cell. |
2. | Mitochondria are primarily involved in the degradation of long-chain fatty acids. |
3. | The outer membrane of mitochondria is highly permeable to protons, helping establish the proton gradient. |
4. | Mitochondria are found only in animal cells and not in plant cells. |
