Mitochondria
Mitochondria are double-membraned, membrane-bound organelles found in the cytoplasm of eukaryotic cells, which are cells with a nucleus enclosed in a membrane. Often referred to as the "powerhouses of the cell," mitochondria play a central role in cellular respiration and energy production.
They generate adenosine triphosphate (ATP), a molecule that stores and releases energy for cellular activities. Mitochondria have their own DNA and ribosomes, suggesting they have a unique evolutionary origin and can partially govern their replication and function. Additionally, they are involved in other cellular processes, such as apoptosis.
