1. Production of ATP (Adenosine Triphosphate): This is the primary energy currency of the body. Cellular respiration breaks down glucose (sugar) in the presence of oxygen to generate ATP. This ATP is then used to power all cellular activities, from muscle contraction to protein synthesis.
2. Release of Carbon Dioxide (CO2): As glucose is broken down, carbon dioxide is released as a byproduct. This CO2 is transported in the blood to the lungs and exhaled.
3. Production of Water (H2O): Cellular respiration also produces water as a byproduct. This water is used to maintain hydration and various bodily functions.
4. Generation of Heat: Cellular respiration is not 100% efficient. Some of the energy released during the process is lost as heat. This heat contributes to maintaining our body temperature.
In summary, cellular respiration in humans is essential for:
* Energy production
* Waste removal (CO2)
* Water production
* Body temperature regulation
