Over the years, the safety of many food additives, from food dyes to trans fats, has come into question. A scare over a food additive may linger in our minds long after researchers find that there's actually no cause for alarm.
In cell biology, a mitochondrion (plural mitochondria) is an organelle found in most eukaryotic cells. Mitochondria are sometimes described as cellular power plants, because their primary function is to convert organic materials into energy.

The mitochondrion (plural mitochondria) is a double membrane-bound organelle found in most eukaryotic cells. The word mitochondrion comes from the Greek Î¼Î¯ÏÎ¿Ï, mitos, i.e. thread, and ÏÎ¿Î½Î´ÏÎ¯Î¿Î½, chondrion, i.e. granule or grain-like.Mitochondria range from 0.5 to 1.0 Î¼m in diameter. A considerable variation can be seen in the structure and size of this organelle. Unless specifically stained, they are not visible.he matrix is the space enclosed by the inner membrane. It contains about 2/3 of the total protein in a mitochondrion. The matrix is important in the production of ATP with the aid of the ATP synthase contained in the inner membrane.
