BIOMOLECULES AND ENZYMES

Detailed explanation-1: -Answer: Because energy is released during the process of respiration, it is an exothermic process. The carbon dioxide in the meal is broken down into glucose during this process. This glucose reacts with oxygen in our cells, releasing a large amount of energy.

Detailed explanation-2: -During respiration, the simpler compounds obtained during digestion are burned to get energy required for various processes. So, respiration is an exothermic reaction since energy is getting released.

Detailed explanation-3: -During respiration, Carbohydrates present in food are broken down to form glucose. Glucose combines with oxygen in the cells of our body and provides energy. Therefore, respiration is an exothermic reaction.

Detailed explanation-4: -Respiration is responsible for breaking down food molecules and releasing energy. Hence it is an exothermic reaction.

Detailed explanation-5: -Chemical reactions that release energy are called exothermic. In exothermic reactions, more energy is released when the bonds are formed in the products than is used to break the bonds in the reactants. Exothermic reactions are accompanied by an increase in temperature of the reaction mixture.
