Mitochondria are bounded by a double membrane. Each of these membranes is a?phospholipidbilayer with embedded proteins. The outermost membrane is smooth while the inner membrane has many folds. These folds are called cristae. The folds enhance the "productivity" of cellular respiration by increasing the available surface area. The double membranes divide the mitochondrion into two distinct parts: the intermembrane space and the mitochondrial matrix. The intermembrane space is the narrow part between the two membranes while the mitochondrial matrix is the part enclosed by the innermost membrane. Several of the steps in cellular respiration occur in the matrix due to its high concentration of enzymes.

Respiration
Cellular respiration is a cycle that occurs in both plant and animal cells. However, note that it does not occur in prokaryotic cells for they lack organelles. The first stage of cell respiration takes place outside the mitochondria and is called glycolosis. Here, glucose is converted to two pyruvates. Then through the Krebs Citric Acid Cycle, the pyruvate is changed to Acetyl-CoA and creates more ATP. Finally, the electron chain results in hydrogen ions being pumped out and then forced to diffuse back and in doing so, produce ATP through facilitated diffusion. In this manner, eukaryotic cells create ATP to power their cells.
