Juliana Park Mayumi Tamada CHEM 111B LAB/ M-F 1-4PM 15 August 2012 Spectroscopy Lab Introduction In this lab, the molar absorptivity of the complex FeLn2+ will be determined by using the absorbance of the complex and its concentration. The absorbance will be found by using a spectrophotometer. For the next part of the lab, the formula of the complex will be determined by also using the volume of ligand and the absorbance again. Experimental There are two different parts to the experiement. In the first part, five 100 mL flasks of 5 mL ligand solution, 5 mL 2 M sodium acetate, 4 mL 3 M NH2OH, and 1-5 mL Fe2+ solution are diluted with water.
This amylase converts the remaining starch into maltose. Maltose and lactose are absorbed into the small intestine. Multiple enzymes reside in the microvilli that lines the small intestine: maltase, lactase and sucrose. They’re called brush border enzymes The brush border enzymes convert the disaccharides into monosaccharides: glucose, fructose, and galactose. The monosaccharides are them absorbed into the bloodstream.
b. Scan the document c. Save the file in your “My Documents” d. Upload the file into Moodle e. Keep the paper copy filed safely as a backup 3) The deadline for completion is Sunday 24th November 2013. Late submissions cannot be awarded a grade other than a pass. 4) The labels have become detached from four containers. The labels indicate that the contents are soluble starch, sucrose (a non-reducing sugar), glucose (a reducing sugar), and albumin (a protein). Solutions have been made from samples of each container, and labelled A, B, C, and D. Use chemical tests to identify each solution.
Stops stomach acid from digesting itself 12. Responsible for most food digestion and all food absorption. 13. A. Support the absorption of carbohydrates and proteins B. accept chyme from the stomach and complete digestion C. Absorbs B12,bile salts, fluids and electrolytes and secretes enzyemes that further break down carbohydrates and proteins 14.
1. What are two major functions o the lymph node. a. Body Defense b. WBC Formation c. Maturation of T Cells d. Storage of RBC’s e. Both a & B f. Both a & C 2. What is a function of the lymphatic system g. Absorb digested fats h. Produce & Mature immune cells i. Reabsorb extracellular fluid & Return it to the bloodstream j.
The small intestine is made up of three sections that help to break down food using enzymes released by the pancreas and bile from the liver. This stage of digestion is where the chemical digestion begins. These enzymes can worth either on the surface or inside the epithelial lining. The ileum is the remainder of the small intestine that is used
1.7 — Submit the completed laboratory report via the Week3 Digital Dropbox by Sunday evening of Week3. Make sure your name is on the laboratory pdf document. Alternatively, you can submit the saved pdf file into the Desktop folder (lastname_iLab3) for later submission to your instructor with the Lab Manual exercises. LABORATORY STEPS PART B: Step 2: Lab Manual Exercise 26: Blood Components and Blood Tests ~ 1 hour From Allen and Harper, Laboratory Manual for Anatomy and Physiology 5th ed. 2.0 — Read background pages 411-423 from the Laboratory Manual.
Use best evidence first then save the worst for last. Always begins with topic sentence. Make sure you use a good choice of vocabulary to keep the readers interested in what you are trying to say. Description Making sure you keep the readers interested using details that involve our senses. Using spatial order, which the writer may go left, right, up or down.
This is an indicatore because sucrase is an enzyme found in the small intestine that catalyzes the splitting of the disaccharide sucrose into the monosaccharides glucos and fructose. The amount of product produced indicate the level of sucrase activity that occured. 5. Explain why denatured sucrase was used as a control. Denatured sucrase was used as a control because denatured enzymes, in this case sucrase, lose their shape and can potentially lose their ability to catalyze a chemical reaction.
A3: Mechanical digestion is the act of physically breaking down food into smaller pieces to aid with chemical digestion. Chewing is an example of mechanical digestion. Chemical digestion is the process where enzymes are introduced into the gut, where it mixes with the food there. The food is at that time, broken down to the molecular level allowing the body to absorb the nutrients for use throughout the body. A4: 1 – Amylase 2 – Lipase 3 – Pepsin 4 – Nucleases 5 – Lactase 6 – Trypsin A5: Research of experiments previously performed can be invaluable when one is looking to design their own experiments to perform.
