Question

What are some examples of chemical digestion?

Answer 1

Chemical digestion:

1. The breakdown of larger molecules into smaller molecules in the gastrointestinal tract is called chemical digestion.
2. This is done with the help of enzymes secreted throughout the digestive tract.
3. It starts in the mouth but is majorly done in the small intestine.

Examples of chemical digestion:

1. Amylase, maltase, sucrase, lactase, etc. convert carbohydrates into monosaccharides and disaccharides in the small intestine.
2. Fats are converted to fatty acids and glycerol by lipases in the small intestine.
3. Trypsin, chymotrypsin, pepsin, dipeptidases, etc. convert proteins into peptones and amino acids in the small intestine.
4. Nucleases, nucleotidases, and nucleosidases convert nucleic acids into nucleotides, nucleosides, sugar, and bases in the small intestine.
