mitochondria (pl)
Normal structures responsible for energy production in cells.

Mitochondria are located in the cytoplasm outside the nucleus of the cell and they consist of two sets of membranes, a smooth continuous outer coat and an inner membrane arranged in tubules or in folds that form plate-like double membranes (cristae).

The mitochondria are the principal energy sources of the cell as a result of the presence of specialized enzymes for terminal electron transport, the citric acid cycle, fatty acid oxidation, and oxidative phosphorylation.

A reference to mitochondria which are the normal structures called organelles (specialized structures) in cells.

They are located in the cell's cytoplasm outside the nucleus.

mitochondrion (s)
1. A small part in a cell that helps the body to turn food into energy.
2. A small spherical or rodlike body, surrounded by a double membrane, in the cytoplasm of most cells which contains enzymes responsible for energy production.
