Question

why is respiration considered as an exothermic reaction?

Answer 1

Respiration involves the oxidation of glucose, to produce energy(38 ATP) from cells.The energy produced is actually heat energy, so, as heat is released,Respiration is an exothermic process.C₆H₁₂O₆+6O₂→6CO₂+6H₂O+energy (38 atp)

Answer 2

Hi there!

Respiration is considered as Exothermic reaction because in Respiration oxidation of Glucose takes place which produces Heat Energy.

This is shown in the following chemical Eqn.

$C_{6}H_{12}O_{6}$ + $6O_{2}$ → $6CO_{2}$ + $6H_{2}O$ + $Energy$
