Question

Why respiration is considered as endothermic reaction

Answer 1

Answer:

Exothermic reactions release heat or energy.When you or we breath out,breath is warmer.This is happened for respiration reaction of our body.

Carbolydrates present in food are broken down to form glucose.This glucose combines with oxygen in the cells of our body and provides energy.This reaction is known as respiration.hence,respiration is considered as an exothermic reaction.

Answer 2

Answer:

Because in respiration energy is used to inhale air and to covert it, ATP are used.

For glucose breakdown, energy is required.

Thus, energy is required in the process.

Thus it is endothermic.
