    The ability of gold ion to bind to a thiol group allows it to bind to proteins in the mitochondrial membrane. When this happens, the mitochondrial membrane becomes more permeable to positively charged ions. This results in decoupling of the oxidative phosphorylation reaction that synthesizes adenosine triphosphate (ATP) (10).
