✓ Correct answer: D. 24In this reaction, 4C<sub>6</sub>H<sub>12</sub>O<sub>6</sub> + 24O<sub>2</sub> will produce 24CO<sub>2</sub> + 24H<sub>2</sub>O + Energy. The balanced equation shows that for every 4 molecules of glucose (C<sub>6</sub>H<sub>12</sub>O<sub>6</sub>), we need 24 molecules of oxygen (O<sub>2</sub>) to completely react. This will produce 24 molecules of carbon dioxide (CO<sub>2</sub>) and 24 molecules of water (H<sub>2</sub>O) along with the release of energy.
