The negative electrode of a fuel cell is called the anode. In the context of a fuel cell, the anode is where the oxidation reaction occurs, typically involving the loss of electrons from the fuel source. This process generates electrons that flow through an external circuit, creating electrical energy.

What are the two different types of cell wall found in eubacteria?
The two different types of cell walls found in eubacteria are gram-positive and gram-negative cell walls. Gram-positive cell walls have a thick layer of peptidoglycan, while gram-negative cell walls have a thinner layer of peptidoglycan surrounded by an outer membrane.
What is a reduction in membrane potential called?
A reduction in membrane potential is called hyperpolarization. This occurs when the inside of the cell becomes more negative than the outside, making it less likely for the cell to generate an action potential.
How is the K transmembrane flux when neurone hyperpolarizes?
The potassium ion channels in the cell open with hyperpolarization (injecting a negative current to take the cell potential more negative than Ek) The potassium ion channels in the cell open with hyperpolarization (injecting a negative current to take the cell potential more negative than Ek)
Do electrons flow from the positive to the negative terminal of a wet cell?
Electrons have a negative charge. For that reason, electrons will always flow in the opposite direction of the current, which flows from positive to negative. Electrons will therefore move from a negative terminal to a positive terminal when we look at the load on a cell. Within the cell, the electrons will flow from the positive terminal to the negative terminal.
Are human cells gram positive?
Human cells are Gram-negative because they do not contain certain structures. More simply, if they don't have a cell wall they cannot be Gram-positive.
What do you call the electrode connected to negative terminal of a cell?
The electrode connected to the negative terminal of a cell is called the cathode.
What is a positive or negative pole of an electrochemical cell?
They are called the electrodes or terminals. The parts of a cell where current leaves and enters the cell. The cathode is the positive, the anode is the negative.
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.
What parts of the cell are used to connect a electrochemical cell to a circuit?
The nodes of the electrochemical cell are called the electrodes. The Cathode is the + end (of a battery). Negative charge enters through it. The - end is called the anode.
Is the anode negative in a galvanic cell?
Yes, the anode is negative in a galvanic cell.
Is the anode negative in an electrochemical cell?

Is the cathode negative in an electrochemical cell?
Yes, the cathode is negative in an electrochemical cell.
Is the anode positive or negative in a galvanic cell?
In a galvanic cell, the anode is the negative electrode.
Is the anode positive or negative in a voltaic cell?
In a voltaic cell, the anode is the negative electrode.
Are anodes typically negative or positive in an electrochemical cell?
Anodes are typically negative in an electrochemical cell.
What are the two different types of cell wall found in eubacteria?

Do gram negative bacteria have peptidoglycan in their cell walls?
No, gram-negative bacteria do not have peptidoglycan in their cell walls.
