Our body is made up of trillions of cells. They  all require energy to function. This energy is   created within ourselves, in the mitochondria.  Here, food is converted into chemical energy   called ATP. ATP is released by the mitochondria,  so cells can use it. Mitochondria consists of two   membranes, an outer membrane separating it from  the cytosol, and an inner membrane surrounding   the so called matrix. The area between these  membranes is called the inter membrane space. ATP   is generated at the inner membrane of mitochondria  by an efficient mechanism called oxidative   phosphorylation, involving several membrane  protein complexes. Nutrients provide high-energy   electrons in the form of NADH, which are used by  the protein complexes to pump protons from the   matrix to the intermembrane space. This continuous  pumping, creates a proton gradient, where the   positively charged protons are attracted to the  more negative matrix. When the protons re-enter   the matrix through the ATP synthase protein  complex, they catalyze the production of ATP.
