Answer: carbon dioxide

Explanation:

Oxidation reaction is defined as the reaction in which an atom looses its electrons. The oxidation number of the atom gets increased during this reaction.

[tex]X\rightarrow X^{n+}+ne^-[/tex]

Combustion is a type of chemical reaction in which fuel is reacted with oxygen to form carbon dioxide and water.

The balanced chemical reaction of oxidation of glucose is given by:

[tex]C_6H_{12}O_6+6O_2 \rightarrow 6CO_2+6H_2O[/tex]

Thus all the carbons of glucose are oxidized to carbon dioxide and all the hydrogens are oxidized to water.

Answer:

They end up being taken by oxygen and turning into carbon-dioxide. That is why we exhale carbon-dioxide.
