Answer 1

In the cellular respiration equation, glucose (C6H12O6) is oxidized, and oxygen (O2) is reduced, leading to the production of carbon dioxide (CO2) and water (H2O).

Step-by-step explanation:

The equation C6H12O6 + 6 O2 → 6 CO2 + 6 H2O + Energy represents a cellular respiration process where glucose is being oxidized and oxygen is being reduced. In this chemical reaction, the carbon atoms in glucose (C6H12O6) lose electrons (and hydrogens) as they are converted into carbon dioxide (CO2), which is a process of oxidation. Simultaneously, oxygen (O2) gains electrons (and hydrogens) as it turns into water (H2O), which is a process of reduction. Therefore, the correct statement is that C6H12O6 is oxidized and O2 is reduced.

In the given reaction, C₆H₁₂O₆ (glucose) is oxidized while O₂ (oxygen) is reduced.

During cellular respiration, glucose is broken down in the presence of oxygen to produce carbon dioxide (CO₂), water (H₂O), and energy in the form of ATP. This process involves the oxidation of glucose, where the carbons of glucose lose hydrogens and form CO₂. On the other hand, oxygen is reduced as it gains hydrogens and forms water.
