2.29 understand the role of digestive enzymes, to include the digestion of starch to glucose by amylase and maltase, the digestion of proteins to amino acids by proteases and the digestion of lipids to fatty acids and glycerol by lipases

Digestive enzymes: important to break down macromolecules into their soluble and absorbably monomers which the body can use for functions such as cell respiration.

Enzyme groups:

Carbohydrase:

Examples

·         Amylase: breaks down starch into maltose

·         Maltase: breaks down maltose into glucose

Protease:

Examples

·         Pepsin: breaks down protein into polypeptides

·         Peptidase: breaks down polypeptide into amino acids

Lipase:

·         Lipase: breaks down fats (lipids) into fatty acids and glycerol
