Respiration is considered an exothermic reaction because it releases energy. In this process, glucose (or other organic molecules) is broken down in the presence of oxygen to produce carbon dioxide, water, and energy. The energy released is used by cells for various functions.
The general equation for cellular respiration is:
C6H12O6 + 6O2 → 6CO2 + 6H2O + energy
Here’s why it’s exothermic:
- Release of Energy: The breakdown of glucose releases energy, which is then used to power cellular activities like muscle contractions, synthesis of molecules, and maintaining body temperature.
