Introduction:
Oxidation is a reaction in which addition of oxygen happens or release of electron takes place of when the release of hydrogen occurs. The oxidation of glucose in the cells occurs along with the formation of ATP (adenosine triphosphate), they are known as the energy currency of the cells. Carbon dioxide and oxygen are also released. When a molecule of glucose undergoes oxidation in the cell, the oxygen molecule reacts with the hydrogen molecules and form water molecules. This entire reaction is named

Answer to Problem 1E
Correct answer:
Option (b) is the correct answer. When glucose compound undergoes oxidation in the cells, oxygen reacts with hydrogen ion and forms water.
Explanation of Solution
Explanation/justification for the correct answer:
Here in this reaction, glucose molecule is oxidized to release carbon dioxide and oxygen is reduced to form water by combining with the hydrogen ions.
This entire reaction can be given by the equation:
Thus, option (b) is the correct answer i.e., oxygen reacts with a hydrogen ion and form water by getting reduced.
Explanation for the incorrect answer:
Option (a) is incorrect since oxygen atoms gain electrons from the hydrogen and not carbon, so it produces water and not carbon dioxide.
Option (c) is also not correct as finally the electron is accepted by oxygen. Oxygen receives this electron directly from hydrogen and forms water molecules.
Option (d) is also incorrect since the formation of ATP is different than this reaction which doesn’t require oxygen atom for that reaction.
Option (e) is not true as the formation of acetate from acetyl CoA involves citric acid cycle or Krebs cycle which doesn’t include oxidation of glucose.
We can hence conclude that option (b) is the correct answer, that is, oxygen reacts with a hydrogen ion and form water by getting reduced.
