The component that is transferred between substances in an oxygen-reduction reaction is electrons.
In an oxygen-reduction reaction, the component that is transferred between substances is electrons.
To understand why electrons are transferred, let's break down the process. In a reduction reaction, a substance gains electrons, while in an oxidation reaction, a substance loses electrons. In the case of an oxygen-reduction reaction, oxygen acts as the electron acceptor, which means it gains electrons.
For example, in the cellular respiration process that occurs in our bodies, glucose is oxidized, and oxygen is reduced. Glucose loses electrons as it is broken down and converted into carbon dioxide and water. On the other hand, oxygen gains electrons to form water molecules.
The transfer of electrons is crucial for chemical reactions as it allows for the conversion of energy. It is the movement of these electrons that generates an electrical current, enabling many biological and chemical processes to occur.
In summary, in an oxygen-reduction reaction, the component transferred between substances is electrons.
