BIOLOGY LABORATORY Biologically Important Molecules Carbohydrates‚ Proteins‚ Lipids‚ and Nucleic Acids Objectives In this lab you will learn to: 1. Perform tests to detect the presence of carbohydrates‚ lipids‚ proteins‚ and nucleic acids 2. Recognize the importance of a control in a biochemical test 3. Use biochemical tests to identify an unknown compound Introduction Organic molecules are those primarily made up of carbon‚ hydrogen and oxygen. The common organic compounds of living

Investigate Concentration of Substrate on Catalase enzyme 1. Aim/Prediction. Aim of this experiment is to investigate concentration of substrate on catalase enzyme‚ as well to see how they work in different concentrations of hydrogen peroxide (H2O2). Prediction would be‚ that the filter paper discs that were used‚ will rise up to the surface in a time in the tube of different concentration of hydrogen peroxide. And in different concentrations the time will be different. As higher the concentration

Restriction Enzymes Restriction enzymes (also known as restriction endonucleases) are a group of bacterial enzymes which cut double-stranded DNA (dsDNA) into smaller fragments at specific points. They are a defence mechanism used by bacteria to cleave the DNA of invading viruses‚ thereby restricting their expression. The exploitation of restriction enzymes ability to cut large pieces of DNA into smaller fragments (called restriction fragments) and the highly specific way in which they do this

Labset Three Worksheet 1. What is a carbohydrate profile? Why are they used as a diagnostic or identifying tool? (2) Carbohydrate profiles are specific information on the type and amount of carbohydrate that a product contains. It is used to identify and differentiate two closely related species. 2. What are the carbohydrate profiles of the organisms you tested? (2) The yeast carbohydrate profile came out with glucose and fructose positive and Mannitol negative. The staph epidermidis

BIO 353 Cell Biology Study Questions for Exam #3 Fall‚ 2012 Cytoskeleton “The harder the conflict‚ the more glorious the triumph.” Thomas Paine... “Unless you really just screw up.” Bush 1. What are microfilaments? (He said know how to identify/draw these) Note: since it is multiple choice‚ I doubt we will have to know how to draw them. **There are also short essay questions and‚ in past classes‚ he has asked students to draw. I thought the final was ALL MULTIPLE CHOICE???********************************

Interactions BigIdea 4 investigation 13 ENZYME ACTIVITY* How do abiotic or biotic factors influence the rates of enzymatic reactions? ■■BACKGROUND Enzymes speed up chemical reactions by lowering activation energy (that is‚ the energy needed for a reaction to begin). In every chemical reaction‚ the starting materials (the substrate(s) in the case of enzymes) can take many different paths to forming products. For each path‚ there is an intermediate or transitional product between reactants and
