Question
The process of respiration is -a) an oxidation reaction which is endo thermicb) a reduction reaction which is exothermicc) a combination reaction which is endo thermicd) an oxidation reaction which is exothermic
Solution
The process of respiration is d) an oxidation reaction which is exothermic.
Here's why:
Respiration is a process in which glucose (or other organic molecules) is broken down in the presence of oxygen to produce carbon dioxide, water, and energy. This process involves the transfer of electrons from glucose to oxygen - this is an oxidation reaction because glucose loses electrons (is oxidized) while oxygen gains electrons (is reduced).
The energy produced in this reaction is released, which makes it an exothermic reaction. An exothermic reaction is one that releases energy in the form of heat or light. In the case of respiration, the energy is used to produce ATP, the energy currency of the cell.
So, the correct answer is d) an oxidation reaction which is exothermic.

Why is respiration considered an exothermic reaction? Explain.
The word respiration is commonly used to describe the process of breathing in oxygen and breathing out carbon dioxide. However, the term more formally refers to the chemical process organisms use to release the energy from food, which typically involves the consumption of oxygen and release of carbon dioxide.
