According to the modern definition, any chemical change in which and element _____ electrons is called a reduction. Loses According to the modern convention, any chemical change in which an element _____________ electrons is called an oxidation.
The gain of electrons is called reduction. Because any loss of electrons by one substance must be accompanied by a gain in electrons by something else, oxidation and reduction always occur together. As such, electron-transfer reactions are also called oxidation-reduction reactions, or simply redox reactions.It is then a straightforward generalization to say that a substance is oxidized whenever it loses electrons, whether oxygen atoms or some other chemical moiety takes up those electrons.

B) The translocation of protons sets up the electrochemical gradient that drives ATP synthesis in. the mitochondria. C) The protons pick up electrons from the electron transport chain on their way through the inner.Substances that have the ability to reduce other substances (cause them to gain electrons) are said to be reductive or reducing and are known as reducing agents, reductants, or reducers. The reductant (reducing agent) transfers electrons to another substance and is thus itself oxidized.
