<P> The intermembrane space is chemically similar to cytosol , but includes a large amount of small proteins as well . As electrons move down the proteins in the electron transport chain , the electrons lose energy to bring H+ ions from the mitochondrial matrix into the intermembrane space . As a concentration gradient of hydrogen ions forms , a protein called ATP synthase harnesses the potential energy of these ions and starts chemiosmosis , where the H+ ions reenter the matrix via this enzyme bound to the cristae ( folds of the inner membrane ) . ADP and a phosphate group are combined to form ATP . </P>
