ATP production in a mitochondrion. Illustration of the enzyme complex that drives the synthesis of the energy-carrying molecule ATP (adenosine triphosphate, red). Known as ATP synthase, the enzyme complex (several shown) is embedded in the mitochondrial inner membrane (orange). The lower part is a channel through which protons (yellow dots) move. The upper part is where ATP synthesis takes place. ATP is formed from a reaction between ADP (adenosine diphosphate) and inorganic phosphate (both shown in orange). The proton gradient (yellow dots inside and outside the mitochondrion) across the
