Alhia Harris October 18‚ 2011 Biology Lab report Proteins are very important throughout the body. They have a lot of functions in cells. Antibodies are proteins that help cells rebuild the cells when they are destroyed. Transport proteins move substances from one place to another. Regulatory proteins control cellular metabolism in a way that cells throughout the body can have the right amount of glucose in the blood. A common protein is an enzyme; in cells they speed up chemical reactions. For

biological molecules to detect the presence of carbohydrates and proteins‚ as well as the action of an enzyme on specific molecules. Introduction Unknown biological molecules can be correctly identified using various tests‚ including colorimetric chemical tests. Colorimetric tests are when a chemical reagent‚ such as Benedict’s‚ is used on a substance or solution and a certain color change occurs as a response. Carbohydrates and proteins‚ two of the larger types of biological molecules‚ also called

3.2.4 Genomic DNA extraction of the root tips After the treatment of the onion bulbs with lake water sample at different period of time‚ the DNA from the root tips will be ready to be extracted and observed. First of all‚ the genomic of the Allium cepa will be easily done by the already available Uneasy® Plant Mini kit (Qiagen‚ Germany) in the laboratory. All of the procedures can be performed by referring to the manual provided by the kit. A very small amount of root tips that weigh 100 mg will

Digestion Lab Abstract – The purpose of this lab was to understand how different solutions played a role in the digestion protein. By looking at different variables‚ such as temperature‚ and pH we’re capable of understanding just how certain substances functioned and when they didn’t. The data for all labs are clear and concise and give a clear understanding of what solutions work best. All three labs were placed in a warm water bath set at 37’C to stimulate the reaction as if it were taking place

absorbed into the blood and carried to cells throughout the body. The things we eat turn into things such as carbohydrates‚ fats‚ and proteins. Carbohydrates are‚ any of a large group of organic compounds occurring in foods and living tissues and including sugars‚ starch‚ and cellulose. Protein‚ such as meat‚ eggs‚ and beans‚ consist of large molecules of protein that must be digested by enzymes before they can be used to build and repair body tissues. An enzyme in the juice of the stomach starts

lipid bilayer of a membrane move from an area of higher concentration to an area of lower concentration. Facilitated diffusion occurs when molecules are too large to pass through a membrane or are lipid insoluble. Thus‚ in the process‚ carrier protein molecules located in the membrane combine with solutes and transport them down the concentration gradient. Hypothesis Activity One: Simple Diffusion- Simulating Dialysis Simple diffusion will occur between different concentrations until equilibrium

Determination of presence of protein in a variety of food substances by the use of Biuret Reagent Biol. 1040 Section 1005 Introduction The human body consumes carbohydrates‚ lipids‚ and proteins each day by eating a variety of foods. These foods are required for energy and human growth. Proteins are a diverse group of macromolecules with many different functions (Mbuthia‚ 2012). Many are structural components of bone‚ muscle‚ hair‚ tissue‚ etc. Others are enzymes that speed up cellular
