how does oxygen helps in buring
Answers
Explanation:
In order to burn this fuel, oxygen is needed, as it is with any fire. The waste products from the combustion process are water and carbon dioxide. Thus, we breathe because oxygen is needed to burn the fuel (sugars and fatty acids) in our cells to produce energy The air we breathe contains about 21% oxygen.
The body can be described as a combustion engine. The fuel needed for this process comprises sugars and fatty acids (fat deposits in our cells), which we gain by eating food. In order to burn this fuel, oxygen is needed, as it is with any fire. The waste products from the combustion process are water and carbon dioxide. Thus, we breathe because oxygen is needed to burn the fuel (sugars and fatty acids) in our cells to produce energy The air we breathe contains about 21% oxygen. This oxygen is brought into the lungs, where it is transported by the red blood cells to the entire body. Once the red blood cells return to the lungs, the "burnt" carbon dioxide is exhaled.
