WebIts absorption is independent of Na + or the transport of glucose and galactose; it is transported instead by facilitated diffusion from the intestinal lumen into the enterocytes by GLUT5 and out of the enterocytes into the interstitium by GLUT2. Some fructose is converted to glucose in the mucosal cells. WebIts main function may be the efficient absorption of nucleosides resulting from the digestion of nucleic acids associated with desquamated enterocytes. Due to the limited de novo synthesis of nucleotides in enterocytes intracellular uptake of nucleosides across the BBM may contribute to nucleic acid synthesis in enterocytes and thus may have a …

23.7 Chemical Digestion and Absorption: A Closer Look

WebDuring this process, proteins are converted into amino acids, carbohydrates are converted into simple sugars and fats are broken down into fatty acids and glycerol. Many digestive enzymes and hormones act on food, at various stages during the process of digestion. The whole process occurs in a sequential manner. Web13 apr. 2024 · 1. Salivary glands: Salivary glands secrete the enzyme amylase in saliva, allowing it to break down carbohydrates. This process facilitates digestion and absorption of essential nutrients in the body. 2. Gullet: In the digestive system, the Oesophagus (food pipe) is located within the Gullet.
