Enzymatic fuel cells control

Bioelectrochemical generation of power by enzymes has also been considered. " " The usage of enzymes as catalysts in fuel cells has been vastly experimented, " and currently some enzymatic fuel cells are being used to produce electricity to power many number of electrical devices, like pumps, valves and pacemakers, or electronic devices, like radios, sensors, controllers, and processors. At present however, enzymatic fuel cells have been... 

Enzymes like PTE rely upon a special kind of molecular assistance to do their jobs efficiently. Metals such as iron, zinc, and copper all perform vital roles in some of the enzymatic reactions that fuel the body s metabolism. Iron, for instance, helps the protein hemoglobin transport oxygen to organs in the body. Many metals act to stabilize the shapes of enzymes. But the body s handling of metals—some of which can be highly toxic in excessive amounts—is a tricky business. In some cases, cells exert exquisitely tight control, assuring that only one or two free metal atoms are present inside an individual cell.
