Question

why respiration is consider as exothermic reaction​

Answer 1

Respiration is considered an exothermic reaction because along with its product, heat is evolved.

When Glucose is broken down by cellular oxygen, carbon dioxide gas, water ATP molecules and Heat are produced

C 6 H 12 O 6 + 6 O 2 --> 6 CO 2 + 6 H 2 O + ATP + Heat

Answer 2

Answer:

during respiration glucose gets oxidised forming carbondioxide and water. C6H12O6----->6CO2+6H2O +energy as the reaction is accompanied by energy it os said to be an exothermic reaction
