Enzymes are catalytic proteins that speed up chemical reactions by lowering the activation energy of the reaction. our body cells depend highly on enzymes to complete many important functions‚ such as digestion and metabolism. Enzymes are selective‚ in which each enzyme can only speed up a specific reaction. There are molecules that enzymes work with called substrates. substrate bind to an area of an enzyme called active site. There is specificity between the enzyme and substrate that react with

Population Gene Pool Simulator‚ PopCycle Abstract The study of microevolution was tested in this laboratory experiment through the examination‚ observation‚ and analysis of various population conditions‚ some under the Hardy-Weinberg Theory of Genetic Equilibrium‚ which would advance the student scientists ’ understanding of both microevolution and the mathematical aspects of microevolution known as population genetics. The students first predicted the result of each of the 6 cases. The data was found using

this lab‚ the dimensions of the knobs produced in one day are tested for discrepancy in order to pass control testing. This lab also reports the probability that knobs with the acceptable dimension will be produced. MATERIALS AND METHODS Using Microsoft Excel‚ a histogram was created displaying the three documented dimensions of 15 batches of knobs. This histogram was obtained in order to provide a clear visible representation of which value occurred most frequently. After this‚ the sample mean

column chromatography. Column chromatography is a method used to separate and purify components in a mixture. In gravity column chromatography (used in this experiment)‚ a vertical glass column is packed with a polar absorbent and a solvent. Then the sample is allowed to pass through the column‚ which separates the different components. In this experiment‚ pigment components

The Effect of Concentration on Absorbance Background Information The purpose of the “Determining Solution ‘Concentration’ Using A Spectrophotometer” lab was to use a spectrophotometer to find the relationship of concentration and absorbance obeying the Beer-Lambert law‚ which states concentration and absorbance are directly related‚ to then further determine the concentration of three unknown solutions. With the assumption that the solutions obey the Beer-Lambert law it is predicted that as concentration

The carbon source Glucose is basically sugar that provides the human anatomy with energy‚ the chemical comes from carbohydrates and in which the body alters into source of energy. Fructose is a monosaccharide which is mainly found in a lot of plants. Fructose is often bonded with glucose and together they form disaccharide sucrose. The organic compound
