The source of electrons can be diverse, but commonly it comes from atoms through processes like ionization, where an electron is removed. In electrical circuits, electrons flow from the negative terminal of a power source (like a battery) to the positive terminal, creating an electric current.
The source of energy that comes from the movement of electrons is electricity.
Electrons in the cathode do not end up because they are continuously being replenished by the power source connected to the cathode. This power source provides the necessary energy to liberate electrons from the cathode material, ensuring a constant supply of electrons available for emission.
The voltage source (such as a battery) is what provides the energy needed to push the electrons through the circuit. Electrons flow from the negative terminal (cathode) to the positive terminal (anode) of the voltage source in a closed circuit.
When a wire is connected to an electrical source, it allows the flow of electrons due to the presence of free electrons within the material of the wire. The electric field created by the electrical source causes these free electrons to move, creating an electric current that can power devices or create electrical effects.
The electrons come from water. In the light dependent stage water is split into hydrogen ions (H+), electrons and oxygen. The electrons are passed on to chlorophyll, the H+ ions combine with NADP to form NADPH and the oxygen is released.
The source of energy that comes from the movement of electrons is electricity.
Electron transport is electricity. Electricity is the flowing of electrons along a substrate such as copper. Electrons will move from one source to another source. In household electricity the electrons travel along the path and back to the original source.

The electrons are always there, for example in the metal. You don't need a special "source" for electrons in a circuit. What you DO need is a voltage source, i.e., something that pushes the electrons around.

The energy source that pushes electrons around a circuit is typically a battery or a power supply. This energy source provides the necessary voltage difference for electrons to flow from the negative terminal to the positive terminal, creating an electric current.
NADPH
The source of electrons in a circuit is supplied by an electric potential difference across two points . This potential difference in a circuit is called as voltage and is measured in joules per coulomb or volts.
The voltage source (such as a battery) is what provides the energy needed to push the electrons through the circuit. Electrons flow from the negative terminal (cathode) to the positive terminal (anode) of the voltage source in a closed circuit.
