Reduction occurs at the cathode in an electrolytic cell. This is where cations in the electrolyte solution gain electrons and get reduced, leading to the deposition of a substance onto the cathode.
The breakdown of molecules to release energy occurs in the mitochondria of a cell through a process called cellular respiration. This process involves the breakdown of glucose to produce ATP, the cell's main energy source, as well as carbon dioxide and water as byproducts.
Mitochondria, which are membrane-bound organelles found in cells, controls the release of energy from food through a process known as cellular respiration. They are often referred to as the "powerhouses" of the cell due to their role in producing adenosine triphosphate (ATP), the main source of energy for cellular activities.
Mitochondria are organelles that are scattered throughout the cell and are responsible for controlling the release of energy from food to form ATP through the process of cellular respiration.
electrolytic cells
electrical energy into chemical energy
In an electrolytic cell, electrical energy is transformed into chemical energy. This occurs when an external voltage is applied to drive a non-spontaneous redox reaction to produce a desired chemical product.
An electrolytic cell uses electrical energy to drive a non-spontaneous chemical reaction, typically involving the decomposition of compounds, while a galvanic (or voltaic) cell generates electrical energy from spontaneous chemical reactions. In an electrolytic cell, the anode is positive and the cathode is negative, whereas in a galvanic cell, the anode is negative and the cathode is positive. Additionally, electrolytic cells require an external power source, while galvanic cells operate independently by harnessing the energy from chemical reactions.

Electrons flow in the opposite direction.
In an electrolytic cell, an external power source is needed to drive a non-spontaneous redox reaction, while in a voltaic cell, the redox reaction is spontaneous and generates electric energy. In an electrolytic cell, the anode is positive and the cathode is negative, whereas in a voltaic cell, the anode is negative and the cathode is positive.

In an electrolytic cell, the anode is positive.
An electrolytic cell requires an external power source to drive the non-spontaneous redox reactions, while a voltaic cell generates its own electrical energy from spontaneous reactions. This external power source is essential for the electrolytic cell to function, as it facilitates the movement of electrons and ions necessary for the electrolysis process. In contrast, a voltaic cell operates independently without needing an external energy input.
A non-spontaneous reaction occurs in an electrolytic cell where an external voltage is applied to drive a chemical reaction that would not occur naturally. In this setup, electrical energy is converted into chemical energy, facilitating processes like electrolysis. For example, the decomposition of water into hydrogen and oxygen gases requires an electrolytic cell to supply the necessary energy to overcome the activation barrier. Overall, electrolytic cells are crucial in various applications, including metal plating and the production of chemical compounds.
