WebMar 26, 2016 · When it comes to oxidation and reduction, keep in mind the following: It’s not only about electrons. When a substance is oxidized, it loses electrons, but it can also lose a proton (H + ). When a compound loses an electron and a proton, it’s actually losing a hydrogen atom (H). Likewise, when a substance is reduced, it can gain a proton. WebMetabolic energy derives from processes of oxidation and reduction.

Compare the two reactions: If respiration (reaction 1) is the complete oxidation of glucose to H2O and CO2, then photosynthesis (reaction 2) is the reduction of CO2 using electrons from H2O. Photosynthesis is thus an endergonic reaction.

WebAnd each of them have an oxidation state of two minus. So these are the half reactions. And all this is showing is that the hydrogen, over the course of this combustion reaction, lost electrons. And that the oxygen gained the electrons that the hydrogen lost. So this tells us that oxygen is reduced.
