Oxidation

Oxidation is a chemical reaction that involves the loss of electrons by a substance. It can also involve the gain of oxygen or the loss of hydrogen. Oxidation reactions often occur in biological systems and are essential for various metabolic processes.

Oxidation in Biology

In biological systems, oxidation reactions are crucial for the production of energy. The process of cellular respiration, for example, involves the oxidation of glucose to produce ATP, the energy currency of the cell. During this process, glucose is oxidized to carbon dioxide and water, and the energy released is used to generate ATP.
