H 2 O Rate Of Reaction
1,374 wordsTitle: The Effects of Substrate Concentration and Temperature on the Rate of Hydrolysis of the Enzyme Trypsin. Abstract: Quantitative measurements can relate both temperature and substrate concentration to the enzymatic activity of trypsin. By analyzing the data, it is suggested that at BAPNA concentrations below those corresponding to Vmax are rate limiting, as less active sights are available for adhesion. The values of Vmax and Km relate a temperate catalytic efficiency of trypsin. The temper...

Parts Per Million Graduated Cylinder
1,007 wordsConcentration of Food Colors in Artificially Colored Beverages Fake Hall rm# 405, SUNY Cobleskill, NY This experiment was performed to investigate and determine the concentration of food coloring in Food Club Brand Cranberry-Ginger Ale. Methods used in the experiment include; comparing the color of the sample to the 3 controls (at 5 ppm, 10 ppm and 15 ppm) by an approximate assessment with just simple eyesight, and the use of a spectrophotometer. The color of the sample of Food Club Ginger Ale s...

Amount Of Light Five Minute
482 wordsDetermining Rates of Photosynthesis Through Chloroplasts 2) Purpose = measure the rate of photosynthesis in chloroplasts. 3) The chloroplast will be subjected to two experimental conditions- light, and the absence of light, using a spectrophotometer to determine the amount of DPIP reduced at specific time intervals under each condition. 4) I predict the amount of DPIP reduced will vary for each condition and increase over the time intervals. I hypothesize under the light condition the amount of ...

Three And Four Reaction Rate
859 wordsTitle: Examining Some Properties of the Enzyme -amylase In this experiment a deeper meaning in the catalysts of reactions is studied. Catalysts accelerate chemical reactions without permanently changing the reaction. Enzymes, catalysts in biochemical reactions, are globular proteins which lower the activation energy needed to begin a reaction and therefore increase the rate at which efficient reactions can occur. Proteins (henceforth enzymes) are complex molecules made of amino acids in polypept...

Test Tube M L
1,232 wordsLab Report 1: Separation of Proteins Abstract/Summary: "Proteins account for more than 50 % of the dry weight of most cells, and they are instrumental in almost everything organisms do" (Campbell, 1999). The significance of proteins to the continuation of our biological systems is undeniable, and a study of how to quantify proteins seems an appropriate introduction to our studies of biology. In order to study proteins we must first know how to separate then quantify the amount using basic princi...

Rate Of Reaction Reaction Rate
1,069 wordsThe purpose of this experiment is to measure the rates of reaction of the enzyme Alkaline Phosphatase with the substrate p-nitro phenol phosphate under varying conditions. The concentration of both substrate and enzyme were diluted and the inhibitor vanadate was utilized to determine whether or not the reaction is substrate or enzyme dependent and to see what type of inhibition vanadate was involved. A class of proteins called enzymes catalyzes almost every chemical reaction in a cell. Enzymes i...

Test Tubes Cell Membranes
1,411 wordsChemical Stress On The Tonoplast Of Beta Chemical Stress On The Tonoplast Of Beta Vulgaris Taproot Cells. Abstract This is an experiment on how chemical stress effects cell membranes, specifically the tono plast of Beta vulgaris taproot cells. This experiment involved the treatment of the aforesaid cells with different concentrations of an acetone solution, and testing the resulting solution for absorbance of light by beta cyanine, using a spectrophotometer. It had been hypothesized that the hig...

Petri Dishes Flowering Plants
3,855 wordsIs there an effect on Rhizobium bacteria by changing its pH? Steve Lincoln Period 3 12 / 7 / 98 Question What are the effects of varying pH levels on Rhizobium bacteria, and can a pH resistant Rhizobium culture be grown? Hypothesis Alterations of the balanced habitat such as the change of pH levels can drastically alter the life of bacteria and can directly affect chemical reactions of enzymes released by the bacteria. Using this information the change in pH will have an effect on the Rhizobium ...
