Assignment Quantitative Analysis of Biomolecules Biochemical analysis involves the characterization of biomolecules within a sample using appropriate laboratory techniques. There are two principal approaches: 1. Qualitative analysis – where a sample is analyzed to determine whether a biomolecule is present or absent. As an example‚ a blood sample might be analyzed for a specific antibody or a bacterial cell might be probed for a nucleic acid sequence. 2. Quantitative analysis – where the quantity

Title: Virus Module: Biochemical Processes______ All viruses are pathogens. Some viruses are deadly‚ for example‚ HIV and Ebola virus. Unlike bacteria‚ fungi and protists‚ viruses do not fit into the framework of cellular organization that is the hallmark of organisms. Bacteria‚ fungi and protists are cells but not virus. Viruses have unique structural and functional properties and cannot reproduce unless they are inside the cell. In fact‚ they can neither generate energy nor make proteins

their food. With the help of saliva produced by the salivary glands‚ which produce enzymes‚ food is able to be broken down further. This is also the place where ingestion takes place” “What are enzymes” “Enzymes are very efficient catalysts for biochemical reactions. In the mouth there’s an enzyme that will help your food undergo chemical digestion” “What is it” “It is amylase. Which help digest starch into smaller molecules. This enzyme will help break down the bread since it is filled of carbohydrates

Biochemistry Exam I Terminology Boiling point is the temperature at which the vapor pressure of the liquid equals the pressure surrounding the liquid. At this temperature the liquid phase changes into the gaseous phase (also a colligative property) Melting point is the temperature at which the solid and liquid phases are in equilibrium. At this temperature the solid state changes into a liquid phase (also a colligative property) Specific heat is the amount of energy (in joules or calories) needed

identification of unknown bacteria is beneficial in many aspects of the research of microorganisms and also aids physicians to treat patients correctly. Various tests were performed to provide the fermentation abilities‚ presence of particular enzymes‚ and biochemical reactions. Qualitative observations were made on the tests in identification process. The data from experimentation provided sufficient results to suggest that the identity of unknown bacterium was the gram-positive spore forming bacteria‚ Bacillus

Biology – HSC Online Extract from Biology Stage 6 Syllabus (Amended October 2002) © Board of Studies‚ NSW 9.2 Maintaining a balance: 1. Temperature range Background: All organisms are adapted to a particular environment with its characteristic temperature range. The temperature range allows the organism’s enzymes to control its metabolism by operating at their optimum efficiency within this range. Some organisms are adapted to live at high temperatures (80 - 100oC) and these are called thermophiles

Biology Revision Notes Biochemical Tests: Proteins - add biurettes reagent to the sample. If protein is present‚ clear colour change from blue to purple. Reducing Sugars – add Benedict’s reagent to the sample. Heat in Bunsen or water bath. If reducing sugars are present‚ clear colour changes from blue -> orange red precipitate. Lipids – dissolve sample in ethanol. Slowly pour the solution into the water slowly. If lipids are present a white emulation forms on the surface. Starch – add iodine

Isolation‚ Morphological‚ and Biochemical Characterization. A high-throughput screening of cartenoid-producing microorganisms resulted in 25 astaxanthin-producing bacterial strains from marine water samples that were collected from the Pacific coast of Japan (unpublished results). Among the isolates‚ a novel‚ highly selective astaxanthin-producing marine bacterium‚ labeled strain (N-5)‚ was isolated based on its ability to produce orange pigment on NA plate after 2 days of cultivation at 30 °C. Strain
