22. 11E: Absorption and Feces Formation in the Large Intestine The large intestine absorbs some of the products formed by the bacteria that inhabit this region Undigested polysaccharides (fiber) are metabolized into short-chain fatty acids by bacteria in the large intestine and get absorbed by passive diffusion
23. 7 Chemical Digestion and Absorption: A Closer Look Most absorption occurs in the small intestine Large food molecules (for example, proteins, lipids, nucleic acids, and starches) must be broken down into subunits that are small enough to be absorbed by the lining of the alimentary canal This is accomplished by enzymes through hydrolysis
6. 3 Lipid Digestion, Absorption, and Transport – Nutrition and Physical . . . Lipids are large molecules and generally are not water-soluble Like carbohydrates, lipids are broken into small components for absorption The main goal of lipid digestion is to remove fatty acids from the glycerol backbone using the enzyme lipase
What happens to chemical bonds when a chemical reaction takes place . . . According to the modern view of chemical reactions, bonds between atoms in the reactants must be broken, and the atoms or pieces of molecules are reassembled into products by forming new bonds Energy is absorbed to break bonds, and energy is evolved as bonds are made
Absorption of Amino Acids and Peptides - Colorado State University These endproducts of digestion, formed on the surface of the enterocyte, are ready for absorption The mechanism by which amino acids are absorbed is conceptually identical to that of monosaccharides
Absorption and Elimination | Digestive Anatomy - Visible Body Finger-like projections called villi line the interior wall of the small intestine and absorb most of the nutrients The remaining chyme and water pass to the large intestine, which completes absorption and eliminates waste
When chemical bonds form is energy absorbed release? When these bonds are broken or formed during a chemical reaction, energy is released or absorbed In a chemical reaction, energy can be both absorbed and released When energy is absorbed,
Exothermic Endothermic Reactions - Foundations By comparing the energy absorbed when bonds in the reactants are broken with the energy released when bonds in the products are formed, you can determine whether a chemical reaction releases energy or absorbs energy overall
The Digestive Process: The Large Intestine - University Hospitals These organs break down food into bits that your body absorbs and uses for energy By the time the food you eat gets to your large intestine, most of the digestion is done The large intestine is also called the colon and the large bowel
