Mitochondrion
The mitochondrion is an organelle found in eukaryotic cells (Tortora 1992). A mitochondrion can occur in different shapes inside one cell. Mitochondrion can be long, like a rod, and filamentous or compact, like a sphere, and granulelike (Wolfe 1993). There are approximately 1700 mitochondria in an average cell. Mitochondrion range from .5 to .1 mm in diameter, which is about the size of a bacterium (Alberts 1983). Mitochondrion contain ribosomes, have their own DNA, can replicate and transcribe their DNA, synthesize enzymes into ATP, and reproduce by growing and dividing (Tortora 1992). Mitochondria are double membrane bound; meaning it has both an outer and inner membrane. The outer membrane is a smooth, continuous covering (Tortora 1992) that appears blue in figure one, below. The outer membrane protects the organelle and is permeable t

The chain's compartments harness this energy and move protons from the matrix to the outer membrane. These folds, know as cristae, give the inner membrane a considerably larger surface area creating a larger space for reactions to occur (Tortora 1992). The bacteria would perform respiration for the host cell and the host would provide nutrients for the bacteria (Encarta 2001). Mitochondria are known as the "powerhouse" of the cell. Separating the outer and inner membranes is an area called the intermembrane space. ------------------------------------------------------------------------**Bibliography**1.
