What is the respiration chemical equation?

The correct answer represents the respiration chemical equation, which is crucial for understanding how organisms convert food into energy. In this process, glucose (C6H12O6) is broken down in the presence of oxygen (6O2) to release energy stored in its bonds. This reaction ultimately produces adenosine triphosphate (ATP), which is the energy currency of the cell, along with the by-products of carbon dioxide (6CO2) and water (6H2O).

This equation reflects cellular respiration, which occurs in all aerobic organisms, allowing them to efficiently harness the energy they obtain from their food. The formation of ATP is particularly significant as it is the primary molecule used for energy transfer within the cell, driving numerous biological processes.

In the context of the other options, they either misrepresent the overall process of respiration or pertain to photosynthesis, which is the reverse reaction, thus outlining the importance of accurately understanding the respiratory process and its role in energy metabolism. Through this chemical reaction, life sustains itself by converting energy from food into a usable form, which is essential for all cellular activities.
