Question

Why is respiration considered an exothermic reaction? Explain.

Answer 1

Energy is required to support life energy in our body is obtained from the food we eat during digestion large molecule of food are broken down into simpler substances such as glucose glucose combine with oxygen in the cell and provide energy the special name of the this combustion reaction is respiration , since energy is released in the whole process is called exothermic reaction

Answer 2

Dear Student,

◆ Exothermic reaction -

• Reactions in which heat is released to surrounding are called exothermic reactions.

# Respiration is considered an exothermic reaction because -

• During cellular respiration, glucose reacts with oxygen to form carbon dioxide and water.
