Use these terms correctly to describe the process of digesting lactose from milk in lactose tolerant individuals: lactose, lactase, digestion, protein synthesis, transcription, translation, polypeptide chain, protein, disaccharide, monosaccharide, milk, mitochondria.
Milk is the source of lactose a sugar which is absorbed in the small intestine. Lactase is an enzyme which breakdown lactose into monomers. Lactase is transcribed in the nucleus of the cell and translated in the cytoplasm into a polypeptide chain. This polypeptide chain further folded and modified into a functional protein. This enzyme can catalyse the digestion of lactose into monomers glucose and galactose. This enzyme is present in the small intestine of human body and can digest lactose containing milk. Lactose is a disaccharide composed of monosaccharides glucose and galactose. This monosaccharide form can be easily absorbed by intestine microvilli structures and transport into the blood. This monosaccharides are transported into mitochondria also known as power house of cell. Mitochondria further breakdown this sugars into ATP molecules which is the primary source of energy in the cells.
