검증된 단계별 안내1
Identify the type of reaction: The given reaction is a cellular respiration reaction, where glucose (C6H12O6) is broken down in the presence of oxygen (O2) to produce carbon dioxide (CO2), water (H2O), and energy.
Understand oxidation and reduction: In a redox reaction, oxidation refers to the loss of electrons, while reduction refers to the gain of electrons.
Determine what happens to glucose (C6H12O6): Glucose is oxidized because it loses electrons as it is converted into carbon dioxide (CO2). This involves the breaking of C-H bonds and the formation of C=O bonds.
Determine what happens to oxygen (O2): Oxygen is reduced because it gains electrons as it is converted into water (H2O). This involves the formation of O-H bonds from O=O bonds.
Summarize the reaction: The correct summary statement is that C6H12O6 is oxidized and O2 is reduced, as glucose loses electrons and oxygen gains electrons during the reaction.
