Electrons flow from the anode to the cathode in a microbial fuel cell as a result of the electrochemical reactions occurring at the electrodes. During the oxidation of organic matter at the anode, electrons are released and travel through an external circuit to the cathode, where reduction reactions occur. This electron flow generates a current that can be harnessed for electricity production.

What is the relationship between the cathode and anode in an electrochemical cell?
In an electrochemical cell, the cathode is where reduction occurs, while the anode is where oxidation occurs. The cathode and anode are connected by an external circuit, allowing for the flow of electrons from the anode to the cathode. This flow of electrons generates an electric current in the cell.
What is the purpose of the anode in an electrochemical cell, and how does it differ from the cathode in terms of their functions and roles within the cell?
The purpose of the anode in an electrochemical cell is to oxidize (lose electrons) and provide electrons to the external circuit. The cathode, on the other hand, is where reduction (gain of electrons) occurs. In summary, the anode releases electrons, while the cathode accepts them, playing opposite roles in the cell's electron flow.
Is the cathode or anode positive in a galvanic cell?
In a galvanic cell, the cathode is positive.
Is it cathode minus anode?
Yes, in an electrochemical cell, the cathode is the negative electrode and the anode is the positive electrode.
In a simple cell the cathode or the anode is more reactive?
In a simple cell, the anode is typically more reactive than the cathode. The anode undergoes oxidation, releasing electrons, while the cathode undergoes reduction, accepting those electrons. This difference in reactivity drives the flow of electrons from the anode to the cathode, generating electrical energy.
In the electrolytic cell electron flows from?
In the electrolytic cell, electrons flow from the negative terminal (cathode) to the positive terminal (anode). This flow allows for the oxidation of ions at the anode and the reduction of ions at the cathode, resulting in the desired chemical reactions to occur.
Electrons in a galvanic cell normally flow?
A galvanic cell is a spontaneous reaction so electron flow will occur as long as a salt bridge is present.

Which electrode, the cathode or anode, is more positively charged in an electrochemical cell?
In an electrochemical cell, the cathode is more positively charged than the anode.
What is the negative electrode of a voltaic cell called?
The negative electrode of a voltaic cell is called the anode. It is where oxidation occurs as electrons are released into the circuit.
Name of one electrode and say is positive or negative?
The Cathode is the negative electrode; the anode is the positive electrode
Which electrode, the anode or cathode, is designated as positive in an electrolytic cell?
In an electrolytic cell, the anode is designated as positive.
Is copper an anode or cathode?
In a galvanic cell or electrolytic cell, the copper can serve as either an anode or cathode depending on the specific set-up and reaction conditions. An anode is where oxidation occurs, while a cathode is where reduction occurs.
