"In a potato battery, the electrical energy is generated by two chemical reactions that happen at the electrodes (the copper and zinc metal strips)."
"The electrons are able to flow through the potato because it acts as an electrolyte"
(Electrolytes are minerals like potassium which is what a potato has)
"The negative side is the source of the electrons that gives the energy to a wire that is connected to an electronic device. Batteries power electronic devices when connected with a conductive material, such as wires."
"Almost all of these minerals participate in or contribute to the chemical reaction with the electrodes resulting an electric flow."
"The potato’s properties allow it to conduct electricity and act as a salt bridge between two metals on either side. This allows the electron current to move freely across a wire in order to create electricity."

To summarize, in a potato battery, the potato acts as an electrolyte, allowing the flow of electrons generated by the chemical reactions at the electrodes (copper and zinc). The potato's minerals, such as potassium, contribute to the chemical reactions and allow for the conduction of electricity. The potato also acts as a salt bridge between the two metals, allowing the free flow of electron current across a wire to create electricity.
