Dictionary » O » Oxidation




(1) The combination of oxygen with a substance forming oxide.

(2) A chemical reaction in which there is the loss of electrons or gain (or increase in the proportion) of oxygen, hence, resulting in an increase in oxidation state by a molecule, atom or ion.

(3) A process resulting in an increase in oxidation number.


For instance in cellular respiration, the oxidation of glucose (C6H12O6) produces CO2.

Word origin: French, from oxider, to oxidize, from oxide, oxide.
Related forms: oxidative (adjective), oxidatively (adverb).

Compare: reduction

Re: Food to ATP energy?

... releases about 7.3 kilocalories in that process. So, the 30 moles of ATP produced can only be converted into 219 kilocalories. That means glucose oxidation releases most of its heat during the process of making ATP (Lucky you!) . Now, 7.3kilocalories is the same as 7,300 calories (or 7.3 Calories ...

Food to ATP energy?

... looses some of the energy as our digestive system does not operate under 100% efficiency. I also suppose some of the energy is lost during the oxidation of those nutritients as well. The rest of the energy is used to convert ATD to ATP. Now, in one of my mothers older medical books, and many ...

Re: Number of water molecules produced by cellular respiration

... suggests (C6H12O6 +6 O2 --> 6CO2 +6H2O). So somewhere else 4 water molecules must be consumed...but where is still a mystery. Maybe in the oxidation reactions of pyruvate that from acetyl CoA or maybe hidden within the reactions of glycolysis, The website: https://www.boundless.com/image/the-citric-acid-cycle/ ...

Re: photoautotroph and photoheterotroph difference?

... Chemoautotrophs, chemoheterotrophs. Both types of phototrophs use light as their energy source ( as opposed to Chemotrophs which use oxidation as their energy source). Photoautotrophs fix inorganic carbon from carbon dioxide into organic carbon in the presence of water. (for example ...
