Does anyone know how tetrazolium cross the membrane to the matrix of the mitochondria? Can I expect that it is hydrophobic enough to diffuse through the membrane? It is a chemical that changes color when reduced. The enzyme responsible is succinate dehydrogenase (oxidizing NADH). Everywhere says that it is a salt. When you look at the structure, there are three phenyl groups hiding the positive charge. Can that be enough to diffuse through the membrane? I highly doubt there is a specific transporter for it.

Thanks in advance.
