Also known as the powerhouse, mitochondria play an important role in respiration where they generate ATP (adenosine triphosphate) from substrates in the presence of oxygen.
Using their DNA, mitochondria are able to encode for some of the components they require to perform their functions.
Mitochondria are partially autonomous organelles that depend on the import of certain proteins and lipids to maintain cell survival and membrane formation.
James Schaffer Essay - Which Organelle Synthesises The Phospholipids That Form The Plasma Membrane
Although phosphatidylglycerol, cardiolipin, and phosphatidylethanolamine are synthesized by mitochondrial enzymes, phosphatidylcholine, phosphatidylinositol, phosphatidylserine, and sterols need to be imported from other organelles.
In eukaryotic cells, the nucleus is enclosed in a nuclear membrane.
It is the organelle that controls the hereditary traits of an organism by directing such processes as protein synthesis and cell division among others.
They protect the cell from external influences, organize the interior in distinct compartments and allow balanced flux of components.
Besides their specific proteome, organelles exhibit unique lipid compositions, which influence their shape, physical properties, and function.
