Chemical Digestion Lab Report
The process of chemical digestion in the breaking down of food with enzymes so that they can become molecules such as nutrients, salts and water , so that way they are easily absorbed and utilized. The process of absorption involves moving such molecules through the GI epithelium and into the blood or lipids. Ingested food is initially broken down mechanically by your mouth into pieces that are easier to swallow, and then broken down again into even smaller pieces so that in can continue its journey through the stomach and into the small intestine. These food particles are primarily made or major nutrients and minor nutrients. The major nutrients such as carbohydrates, protein and lipids must be broken down further enzymatically in order to
Fetal Pig Lab Report
926 Words | 4 PagesThe digestive system is responsible for chemically and mechanically breaking down food and includes organs such as, mouth, esophagus, stomach, small intestine, rectum, anus, and additional accessory organs. These organs all aid in the breakdown of food. Food is broken down mechanically by chewing and churning in the stomach, and chemically by acidic enzymes in the stomach and in the small intestine which receives enzymes from the pancreas that are specifically designed for the breakdown of nutrients. Once the food and nutrients are broken down, the excretory system removes whatever the body decides is waste by filtering blood in the nephrons of the kidneys and turning it into urine which is then collected in the bladder and removed from the body when the bladder is

Analysis Of Gaseous Products Lab Report
1176 Words | 5 PagesIn this experiment, Analysis of Gaseous Products, a comparison between the elimination reactions created in the presence of an acidic and basic conditions was observed to be further analyzed through gas-liquid chromatography. These conditions were achieved by acid-catalyzed dehydration of a secondary and primary alcohol and based-induced dehydration of a secondary and primary bromide. As a result of these changing eliminations, gas-liquid chromatography makes it possible to separate and isolate volatile organic compounds to analyze the stereochemistry and regiochemistry of these compounds without decomposing them. Overall, gas-liquid chromatography of these compounds in acidic or basic conditions contributed in the identification and analysis
Digestive System Research Paper
917 Words | 4 PagesThere is also strong acid released by the glands in the lining of the stomach which helps break down food into a more useable form and also aids in the destruction of most ingested bacteria. After the contents have successfully been broken down they are released into the small intestine. The small intestine is a 22 foot long tube that helps to break down the food with enzymes released from the pancreas and bile released form the liver. In this organ the process of Peristalsis is at work, pushing the food further and further through the small intestine towards the colon. These movements are stimulated by the presence of chyme.
Gas Chromatography Lab Report
1545 Words | 7 PagesINTRODUCTION A gas chromatograph (GC) can be utilized to analyze the contents of a sample quantitatively or in certain circumstances also qualitatively. In the case of preparative chromatography, a pure compound can be extracted from a mixture. The principle of gas chromatography can be explained as following: A micro syringe is used to inject a known volume of vaporous or liquid analyte into the head or entrance of a column whereby a stream of an inert gas acts a carrier (mobile phase). The column acts as a separator of individual or chemically similar components.
Lab Report On Acid Base Titration
1346 Words | 6 PagesPractical I: Acid-base equilibrium & pH of solutions Aims/Objectives: 1. To determine the pH range where the indicator changes colour. 2. To identify the suitable indicators for different titrations. 3.
Lab Report On Fermentation
1432 Words | 6 PagesJoshua Miller 12/18/17 Fermentation Lab report Introduction The term fermentation refers to the chemical breakdown of a substance by bacteria, yeasts, or other microorganisms, typically involving effervescence and the giving off of heat (wikipedia). Sugars are converted to ethyl alcohol when fermentation happens. In this experiment we determined if yeast cells undergo fermentation when placed in a closed flask with no oxygen. Glucose and yeast are mixed together in a closed flask and allowed to incubate for about one hour.
Biochemical Test Lab Report
1371 Words | 6 PagesBiochemical tests are the tests used for the identification of bacterial species based on the differences in the biochemical activities of different bacteria. Bacterial physiology differs from one species to the other. These differences in carbohydrate metabolism, protein metabolism, fat metabolism, production of certain enzymes and ability to utilize a particular compound help them to be identified by the biochemical tests. Gram’s stain was originally devised by histologist Hans Christian Gram in 1884. Gram-positive bacteria stain purple, while Gram-negative bacteria stain pink when subjected to Gram staining.
