GradeBuddy is best used as a supplement to your own notes, not as a substitute.Carbohydrates begin breaking down in the mouth, beginning with breakdown through the enzyme in salvia known as amylase. This then forms a bolus that moves down the esophagus, which is made up of smooth muscle. Peristalsis is the process that moves food down the esophagus. The fish gets digested in the stomach. Pepsin in the enzyme that breaks down proteinMacromoleculeFinal digested monomers that are Location(s) of macromolecule Names of enzymes that act Digestion in mouth?Digestion in stomach?Digestion in intestine?3 types of cells:1.2.3.____________________:The Duodenum.What happens here?absorbed digestion on each macromoleculeCarbohydrateFructose and glucose (monosaccharides)Mouth, stomach, small intestineAmylaseProtein Amino acids Stomach, small intestine pepsinLipids Glycerol and fatty acids Small intestine lipaseNucleic Acids Nucleotides Small intestine Nuclease 3 cells 1. Chief Cells – secrete pepsinogen2. Parietal Cells – secrete HCl3. Mucus Cells – secrete mucus which protects the stomach from acidWhat happens in the duodenum?- the liver is the site of bile production- the gall bladder is the site of bile storage- the bile breaks down the fats into droplets so that they are more susceptible to enzymatic activity- the pancreatic juice contains enzymes which are released out for further breakdown.- Pancreatic juices neutralize the acidity of the acid chymeDigestion in the small intestine – all other macromolecules except for plant based carbohydratessuch as fiberCecum – the end of the small intestine, which is home to some intestinal bacteria. Some bacteria that live in the cecum of animals that can break down plant carbohydrates; they are smaller in carnivores bc they do not ingest a lot of plant material so they don’t need to digest those
