What is the form of energy acquired from food?

1 Answer

It's known as a Calorie, which is then stored as potential energy in the form of chemical bonds or chemical energy


The food that you eat is eventually broken down into three main typical of chemicals: carbohydrates, proteins(amino acids), and fats. The energy is stored in the chemical bonds of the these molecules. These molecules are eventually processed to make the energy molecules called ATP that provides energy that the body needs.

So food energy is also called chemical energy. Fundamentally, chemical bonds are electrical in origin, as molecules are made of nuclei with positive charge and electrons with negative charges. When chemical reactions happened, nuclei and electrons are reshuffled, giving up the electric potential energy stored in these molecules.

The pathways food into energy is best illustrated here.http://chemistry.elmhurst.edu/vchembook/620fattyacid.html
