Why is respiration considered an exothermic reaction?
Answer
Respiration is an exothermic reaction because it breaks down glucose and releases energy in the form of heat and ATP.
The working
Meaning of exothermic
An exothermic reaction is one that releases energy to the surroundings, usually as heat.
What happens in respiration
During respiration, glucose combines with oxygen and its bonds are broken to release a large amount of energy.
Energy released
This energy appears partly as ATP and partly as heat, which is why our bodies stay warm; hence respiration is exothermic.
Evidence
The warmth of the human body is direct proof that respiration continuously releases heat energy.
