When large molecules are broken down they actually turn into a different substance. Proteins break down into amino acids. Lipids break down into fatty acids. Carbohydrates break down into simple sugars. And those are just a few of them. Large molecules need to break down so that they can change into other substances so they can dissolve or help the body another way.
so that you can eat food
Most large insoluble molecules get broken down in the digestive system to small (simpler) soluble molecules.
Digestive system
Digestive System.
Food molecules are pieces of food broken up by acid juices in the digestive system.
So that large, insoluble molecules of food can be broken down into smaller, soluble ones which can then be absorbed into the bloodstream for use by all the cells in the body.
The digestive system break down larger insoluble food molecules into smaller soluble one. hope this helps lily-may
First the food we eat is divided into smaller pieces and the nutrients are separated with the help of Digestive System which are further transported to other parts of our body with the help of Blood Circulatory System.
Cells receive nourishment from the blood. The blood carries molecules that are broken down from food in the digestive system.
Digestive system
it is different cause they are smaller
The first task of the digestive system is to break down food into a fine pulp (mechanical digestion). When the food is physically broken down, digestive chemicals break the food down into small molecules (chemical digestion). The mouth is the organ in which the process of digestion begins.(Google)
They are broken down into simpler molecules by the digestive system so they can be absorbed into the bloodstream.
