Oxidation

Definition

noun

(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.


Supplement

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).

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 ...

Is energy released or not released during the reduction of N

The energy is not released during both reduction of oxygen and oxidation of glucose, but only during the oxidation of glucose and this energy is then used for the reduction of oxygen.

Is energy released or not released during the reduction of N

... make sense to me because I am of strong belief that all redox reactions are exergonic. For example the reduction of oxygen molecules following the oxidation of glucose releases a lot of energy. is the reduction of NAD a special case in which more energy is absorbed than released? And if it is a ...
