NEET BIOLOGY

Detailed explanation-1: -Through the process of cellular respiration, the energy in food is converted into energy that can be used by the body’s cells. During cellular respiration, glucose and oxygen are converted into carbon dioxide and water, and the energy is transferred to ATP.

Detailed explanation-2: -Cellular respiration is a metabolic pathway that breaks down glucose and produces ATP. The stages of cellular respiration include glycolysis, pyruvate oxidation, the citric acid or Krebs cycle, and oxidative phosphorylation.

Detailed explanation-3: -Chemical energy in food The food we eat contains stored chemical energy. As the bonds between the atoms in food loosen or break, a chemical reaction takes place, and new compounds are created.

Detailed explanation-4: -In food, it’s a form of potential energy because it’s stored away. Then, through a process called chemical digestion, the bonds containing the stored energy are broken, releasing energy that our bodies then use. Chemical energy can also be converted from one form to another.
