just seen, water molecules are important to hydrolytic reactions critical to digestion. Describe other critical water uses.Liquefaction and Transport: in the canal water helps liquefy foodstuffsSecretion Transport: accessory digestive organsNutrient Absorption: water plays an important role in the absorbing of nutrients.7.The stomach produces hydrochloric acid. How is HCl critical to the following?Pepsin (a gastric enzyme): alters the globular shape of proteins to promote production of pepsinProteins: alters the globular shape of proteins to promote the destruction of microbial proteins8.Describe the following regarding bile. Source (organ): produced by the liverMolecular structure: mostly bile salts (produced by cholesterol) and waterPrimary function: emulsification of fatty globulesEmulsification need: breaks down fatty molecules by lipase enzymes9.Describe bicarbonate functions.Intestinal protection: Bicarbonate is secreted in the intestine to buffer the acidic chyme from the stomach and protect intestinal mucosaIntestinal enzymes:Bicarbonate is secreted in the intestine to promote an alkaline PH level in the small intestine to create a proper environment for intestinal enzymes to function normally
