Question

Why is respiration considered as an exothermic reaction? Explain
Define Rancidity?​

Answer 1

It involves the burning of sugar with oxygen within the cells of every living organism, to produce the energy needed for all the reactions of life along with water and carbon dioxide as waste products. Respiration is another exothermic reaction.

RANCIDITY÷having a rank, unpleasant, stale smell or taste, as through decomposition, especially of fats or oils: rancid butter. (of an odor or taste) rank, unpleasant, and stale: a rancid smell.

hope you understood.

Answer 2

It is considered as an exothermic reaction because it involves reaction of glucose and oxygen and gives out energy where most of the energy is stored in ATP molecules.

rancidity: Hydrolysis of fats and oils when exposed to air, moisture, etc.
