BIOL 101 1st Edition Lecture 26 Outline of Last Lecture I Animal Tissues II Major Vertebrate Systems III Tissues Work Together a Types of Tissues Outline of Current Lecture I Digestion II Macromolecule Breakdown III Types of Cells IV Duodenum V Cecum Current Lecture Class Discussion Digestion These notes represent a detailed interpretation of the professor s lecture GradeBuddy is best used as a supplement to your own notes not as a substitute Digestion in mouth The Duodenum What happens here Digestion in stom Digestion in intestine 3 types of c 1 2 3 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 protein Macromolecul e Final digested monomers that are Location s of macromolecule Names of enzymes that act absorbed digestion on each macromolecule Fructose and glucose monosaccharides Mouth stomach small intestine Amylase Protein Amino acids Stomach small intestine pepsin Lipids Glycerol and fatty acids Small intestine lipase Nucleic Acids Nucleotides Nuclease Carbohydrate Small intestine 3 cells 1 Chief Cells secrete pepsinogen 2 Parietal Cells secrete HCl 3 Mucus Cells secrete mucus which protects the stomach from acid What 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 chyme Digestion in the small intestine all other macromolecules except for plant based carbohydrates such as fiber Cecum 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 carbohydrates
