absorption
Hydrolysis and other chemical reactions are used during the process of digestion to break large molecules down into their smaller components. Hydrolytic reactions are exergonic reactions.
Hydrolysis
Fatty acid molecules and glycerol
The secrete gastric juice and the digestive hormones are secreted from the small intestines during the digestion process.
Enzymes are needed during the process of digestion.
The Liver.
Basically, the process of digestion causes large, complicated molecules to become smaller, simpler molecules. Proteins become amino acids. Starches become sugars. And so forth. Some chemicals remain unchanged; not everything needs to be altered to be digestible.
The small intestines absorb most of the water during digestion.
