Participates in maintaining the colloidal properties of the cytoplasm (reduces the viscosity);

participates in the creation and maintenance of bioelectric potential on the membrane (as a result of the operation of a sodium-potassium pump);

activates enzymes for protein synthesis;

it is a part of the enzymes involved in glycolysis

It is involved in maintaining osmotic pressure (regulating the water regime); it is involved in regulating stomatal movements; it is a part of enzymes involved in photosynthesis. (The usual component of cell juice in plant cell vacuoles is contained in the form of K+ions.) Participates in maintaining the heart rate (together with sodium and calcium); participates in conducting a nerve impulse
