    Cofactor, ie Cl- ions. How it binds elsewhere onto enzymes, allowing it to form ESC more easily as flexibility of active site increase, form more bonds from R groups in amino acids of enzymes active site, weaken the bonds, lower activation energy, converted to product. Something along them lines
