vaporization. Usually accomplished by excessive heating. Although it depends on which object you are talking about.
Yes.
they break down larger molecules If a cell organisation is disturbed , lysosomes break down and digest.
Hydrolysis
No, starch can not break down fat. they are different bio-molecules.
Enzymes
When living cells break down food molecules energy is released and used to form ATP.
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.
The enzymes like pepsin break down the proteins and not the other molecules because they are themselves protein.
They break down
Both prokaryotic and eukaryotic organisms break down molecules to produce energy.
The Enzymes speed up the process in which orgaic molecules breakown. They help the molecules break down. Therefore speeding up the process. Thats the Low-down. Hope it helped :)
To break down the food molecules.
