Just one great candidate for a web-site of motion of modafinil within the mitochondrion is cytochrome c or an enzyme that reacts with it. Cytochrome c functions within the mitochondrial electron transportation chain Ordinarily to maneuver electrons from complex III to sophisticated IV to create h2o, but It is usually capable of being introduced in the internal mitochondrial membrane and accepting electrons from hydrogen peroxide in the intermembrane Room or superoxide created by complicated I (see Skulachev [1998] for critique).
