The number of oxygen molecules that will be required to completely oxidize a molecule of glucose to carbon dioxide and water during respiration would be 6.
During respiration, oxygen reacts with carbohydrates to produce energy in the form of ATP while carbon dioxide and water are released as by-products.
The reaction takes place through a series of steps, but the overall equation of the reaction is as follows:
[tex]C_6H_1_2O_6 + 6O_2 --- > 6CO_2 + 6H_2O + ATP[/tex]
Thus, for every one molecule of carbohydrates, 6 molecules of oxygen are needed for complete oxidation.
