Mar 5, 2023 · An oxidation-reduction (redox) reaction involves the transfer of electrons between two species. In such reactions, one species loses electrons (is oxidized) while the other gains electrons (is reduced). To determine whether a species is an oxidizing agent or a reducing agent, we need to look at its ability to accept or donate electrons. The electron on the lowest step has a large arrow pointing from the electron to an image labeled ATP. The electron on the lowest step also has an arrow pointing towards an electron at the base of the steps, and next to that electron is a chemical formula that says electron plus oxygen plus 2 hydrogen ions produces water.The gain of electrons is called reduction.
