Food energy is measured in Calories. A Food Calorie is 1 Kilojoule, or 1,000 Science Calories.
Your body delivers nutrients into the blood through the food that you eat. As food is broken down the nutrients are absorbed into the blood stream and are then carried to tissues and organs throughout the body.
When molecules are broken down the energy is released from the outer electron shells of the various elements involved.
When a hemoglobin molecule is broken apart, the iron pigment is released. This is what is called the -"heme" part of the molecule.

There are several nutrients that are required by the human body that are not broken down by the body or destroyed by heat, including:* ...* ...* calcium* iron* ...
Nutrients go into for eg. the soil, or in the case of decomposers, they use the nutrients for themselves.
There are commonly know to be only 3 main nutrients which are carbohydrates, proteins, and lipids (fats). Lipids are broken down into fatty acids and glycerol. Proteins are broken down into amino acids, and carbohydrates are broken down into simple sugars like glucose.
nutrients aren't broken down in the liver. Any nutrients carried their are used by the liver itself to repair, grow and to function
"Lysosomes"
food isn't exactly broken into molecules. molecules are collections of atoms. those would be too small to see. but food is broken down so the nutrients can be gathered. the food is broken down in the stomach, then, the food goes through the intestines where the nutrients and water are gathered
