The correct answer is option A."Glucose loses electrons and hydrogen to form carbon dioxide".
Explanation:
An oxidation reaction is characterized by a reactant losing electrons, which results in the reactant having an oxidized state. An example of oxidation reaction that occurs during cellular respiration is glucose losing electrons and hydrogen to form carbon dioxide. In cellular respiration, glucose is broken down to produce ATP and carbon dioxide as byproduct. During the reaction glucose reacts directly with oxygen, which makes glucose into a higher oxidized state.
