Question

Glucose reacts with oxygen in the cells of our body and provides energy.

Hint:

Balancing chemical equations requires ensuring that the number of atoms on both sides of the equation is the same. In combustion and respiration reactions, oxygen is crucial, and the products are often carbon dioxide and water.

Answer 1

Glucose (C₆H₁₂O₆) combines with oxygen (O₂) in our bodies, yielding carbon dioxide (CO₂), water (H₂O), and energy. This is cellular respiration, an exothermic reaction supplying cellular energy. The balanced chemical equation is:\[C_6H_{12}O_6 (aq) + 6O_2 (g) \rightarrow 6CO_2 (g) + 6H_2O (l) + \text{energy}\]This reaction generates the energy required for bodily functions.
