4. manganese
   An essential trace element. Present in cells as concentrations of around 0.01mM. Activates a wide range of enzymes eg. pyruvate carboxylase and one family of superoxide dismutases. Resembles magnesium and may replace it in many enzymes when it can modify substrate specificities. The addition of manganese salts to buffer solutions will often make cells very adhesive.
