Cellular Respiration

Mitochondrion is a membrane enclosed organelle found in most eukaryotic cells. It contains an outer and inner membranes composed of phospholipids bilayers and proteins. The main function of mitochondrion is the production of energy, in the form of ATP, The cell uses this to perform the specific work necessary for cell survival and function. The tissues in the body are broken down into simpler molecules such as carbohudrates, fats and protein in called metabolism. 

Some other interesting things about mitochondria are :

It is the second largest organelle with unique genetic structure
- Double-layered outer membrane with inner folds called cristae
- Energy-producing chemical reactions take place in here
- Controls level of water and other materials in cell
- Recycles and decomposes proteins, fats, and carbohydrates, and forms urea
