Investigating the Enzymatic Activity of Catecholase through Temperature‚ pH‚ Enzyme Concentration‚ and Substrate Concentration University of Alabama at Birmingham Burgess‚ B.N. Introduction: Background Enzymes are macromolecules that act as catalysts in living organisms by speeding up chemical reactions without being changed or destroyed by the reaction (Campbell and Reece‚ 2008). Enzymes are able to speed up the rate of a chemical reaction by decreasing the activation energy during the reaction

NAME: Donna Ha TITLE: Measuring the Rate of Osmosis Using “De-shelled” Chicken Eggs INTRODUCTION: In order to fully understand the concept of this experiment‚ one must first be introduced to diffusion. Diffusion is a spontaneous process by which molecule particles move from one area that is highly concentrated to another area in which its concentration is lower. Cells contain fluids and are surrounded by fluids; in order for a cell to function it is required to be in a balanced state. The

Photosynthesis and the Amount of Light _______________________________________________________________________ I. Introduction Photosynthesis the process where plants use sunlight (energy) to synthesize foods forming the products carbohydrates and water (H20 + CO2 + Light CH2O + O2). For photosynthesis to take place they need water‚ carbon dioxide and light and chloroplasts. Light is absorbed inside he thylakoid

This reflects accurate results reproduced by another experiment performed by Campbell et al (2004). When looking at the effects nicotine and ethanol had on the heart rate of the Daphnia magna‚ it showed that they were depressants by the decrease in the Daphnia’s heart rate in comparison to the heart rate of the control group. The results of Ceballos et.al (2010) supported the results obtained in this experimental. Ceballos et.al (2010) experiment analyzed further and noticed that the nicotine had different

Enzyme lab report. Introduction. An enzyme is a protein molecule that speeds up the rates of chemical reactions by many folds. They recognize‚ bind‚ and change specific reactants. They do not change thus can catalyze the same reaction again and again. Activation energy also known as an energy barrier is the amount of energy needed in order to begin a chemical reaction. Catecholase catalyzes the reaction rate of catechol oxidation. Catechol is found beneath the skin of many plants such

In the humus lab were were trying to find out if hydrogen peroxide would cause a reaction and show us the amount of humus in the soil by putting gas into a graduated cylinder with water to make the water level lower therefore showing us how much humus the material being tested contained. It showed that the sand was lacking humus but the mushroom compost was the most rich in humus. My hypothesis was correct because I predicted that the mushroom compost would produce the greatest amount of humus out

Biophysical Ecology Abstract: There are many patterns that can be observed throughout our environment. In this experiment‚ the temperatures of organisms in a biophysical environment were analyzed to see if a pattern could be recognized that was related to the behavior of an ectotherm. An ectotherm is an organism that relies on the environment to regulate its body temperature. Organisms such as Pseudemys (turtles) and Lacertilia (lizards) are examples or ectotherms. After arriving at Maxcy Gregg

temperature disrupts the structure of proteins and certain chemicals such as acetone and methanol dissolve the phospholipids‚ leading to damage of the membrane and therefore leads to increased permeability. Beetroot is the material used in this experiment to demonstrate the effects of high temperature and chemicals on the permeability of the cell membranes. Beetroot contains a red pigment called betacyanin‚ which is located in the large central vacuole of the beetroot cells. The vacuole is enclosed
