Accordingly, what is the difference between digestion absorption and metabolism?

The misunderstood relationship between digestion and metabolism. To start, some definitions: Digestion refers to how the body processes food in the gastrointestinal (GI) tract and eliminates food waste via the intestines. Metabolism refers to how the cells utilize the energy we have absorbed from food during digestion.

Secondly, how are fats digested and absorbed? Lipids, or fat, go undigested in your digestive tract until they reach your small intestine, where they meet bile. Bile contains bile salts, which act as an emulsifier of lipids. This breaks the large fat droplets into smaller droplets that are then easier for the fat-digesting enzyme pancreatic lipase to digest.

Beside this, how does the digestive system help with metabolism?

After we eat food, the digestive system uses enzymes to: break proteins down into amino acids. turn fats into fatty acids.

How proteins are digested and absorbed in the body?

Protein digestion occurs in the stomach and duodenum in which 3 main enzymes, pepsin secreted by the stomach and trypsin and chymotrypsin secreted by the pancreas, break down food proteins into polypeptides that are then broken down by various exopeptidases and dipeptidases into amino acids.
