For example, enzymes in the body can't catalyze chemical reactions, carriers on the surface of cell membranes can't transport nutrients and excrete metabolic wastes, and myosin and actin can't complete muscle contraction, so cells in the body can't get nutrients, eliminate wastes, generate energy, and the cell structure collapses and loses its function.
It is worth mentioning that it is not only excessive intake of harmful metals that will lead to metal poisoning, even if the human body needs too much metal intake, it will also lead to poisoning.
