Food is broken down into nutrients by the digestive system. Ingested food is transformed into usable nutrients by mechanical and chemical processes in the digestive system.
Digestive system
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 are absorbed into the bloodstream. Starch is broken down by enzymes. Macromolecules are broken down.
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
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.
"Lysosomes"
The digestive system breaks food down into useful nutrients.
When an organism dies, it is broken down into nutrients by bacteria, which can be absorbed by plants.
During metabolism, energy nutrients are broken down and distributed to cells throughout the body. These nutrients are used to power cell functions.
Foods are broken down by digestive juices into nutrients. These nutrients are carried carried throughout the body and broken down into carbohydrates, protein, vitamins and fats which are used for energy, cell repair and growth. Digestion starts in the mouth with the saliva and ends in the large intestines and exits through the anus and rectum. Proteins are broken down into amino acids. Starches are broken down into sugars. Etc.
Nutrients need to be broken down into smaller molecules so that they can be absorbed and utilized by the body. This process allows the nutrients to be transported through the bloodstream to cells where they can be used for energy, growth, and repair. Additionally, breaking down nutrients releases the energy stored within them for various biological processes.
Once food is broken down during digestion, the nutrients are absorbed by the body to provide energy, support growth and repair, and maintain overall health. The body uses these nutrients to fuel various bodily functions and processes. Any excess nutrients are stored for future energy needs.
