Yes, "calories" are a measurement of energy that is contained in the food you consume.
The chemical energy of food provides energy to us. When food is burnt, energy is released.
chemical energy
The energy released from food after it is eaten is in the form of chemical energy. This energy comes from the breaking down of molecules in food through digestion, which releases stored energy that the body can then use for various functions.
It is in movement
Heat energy, mechanic energy, and new chemical energy.
It is essentially chemical energy, which is released when the food is digested in the stomach
No, the body has to process the food before the energy can be accessed.
The energy released from food after it is eaten is in the form of chemical energy. This energy is stored in the chemical bonds of the food molecules and is extracted through cellular respiration to fuel various metabolic processes in the body.
mitochondrion
Energy.
Heat energy
Digestion is necessary because for energy from the food to be released and carried into the cells in our body the food must be broken down into soluble molecules for it to diffuse into the cells. Then energy is released during respiration.
