Design your own experiment: Effect of pH on enzymatic activity Background Information: Trypsin is a protease which conducts hydrolysis forming peptides. It is an enzyme which is secreted by the pancreas into the small intestine and works best in an alkaline environment. Egg white is used in this practical as it is found to contain the protein/ enzyme trypsin. pH is the measure of the amount of H+ ions in a solution‚ these ions affect the shape of the enzyme. Hypothesis: That as pH increases

What effect does temperature have on the oxygen production of enzymes in an animal’s liver? A temperature which is too high would be able to produce little to no oxygen because of the extreme temperature. Just like a temperature too high‚ a temperature which is too low would also produce little to no oxygen for the same reason. Animals that have livers are considered warm-blooded‚ with very warm temperatures; therefore it would make sense for a warm temperature to produce the most oxygen; but one

Environment Can Effect Enzymes Introduction: In a chemical reaction there sometimes can be a catalyst present known as an enzyme. An enzyme is a protein that speeds up a chemical reaction by lowering the amount of activation energy required to start the reaction. By lowering the activation energy‚ more of the substrate is able to participate in the reaction‚ speeding it up. Enzymes are substrate specific. The substrate is what the enzyme bonds to. That is to say that enzyme A will only react with

Abstract: This lab tests how temperature and pH affect how enzymes will function. The lab showed that temperature will denature an enzyme when past its optimal working temperature and won’t denature in cold temperatures‚ but have slowed molecular activity. pH will also have an affect on an enzymes efficiency‚ when out of optimal pH the enzyme will not function as it is supposed to and if to far out of the optimal pH the enzyme will change shape and no longer work. Enzymes also showed to be reusable

Introduction: Capture and recapture is a method to observe animals‚ give information on survival‚ recruitment‚ and size of the population. You capture the animals and mark them and release them. Mark and release repeatedly. Objective: The purpose of this experiment was to analyze the amount of marked beans of the beans we would catch. Hypothesis: If the number of marked beans represents the number of the mocking jays in the forest and the unmarked beans are the food supply then the mocking jays population

Enzyme Kinetics Marcos‚ Nelissa S. Institute of Chemistry‚ University of the Philippines‚ Diliman‚ Quezon City 1101 Philippines ABSTRACT The rationale of the experiment is basically founded in the concept of reaction rates as affected by enzyme‚ and how the enzyme works is competed by a competitive inhibitor‚ thereby impeding the forward reaction. In this experiment‚ o-diphenol oxidase‚ an enzyme that causes the browning in fruits‚ was extracted from banana and reaction rate of this was established

Objective: One objective was to figure out if the burnt Mg ashes weigh more than the product which is Magnesium Metal. Another objective was determining the formula of the compound that results when Magnesium and Oxygen react. Theory: The purpose of this lab was to confirm the chemical formula of magnesium oxide by comparing the masses of pure magnesium solid prior to any reaction and magnesium oxide solid after a reaction between all of the magnesium and oxygen from the air when heated from a Bunsen burner

Enzymes Enzymes are the sparks that start the essential chemical reactions our bodies need to live. They are necessary for digesting food‚ for stimulating the brain‚ for providing cellular energy‚ and for repairing all tissues‚ organs‚ and cells. There are three types of enzymes: metabolic enzymes‚ digestive enzymes‚ and food enzymes. Metabolic enzymes catalyse‚ or spark‚ the reactions within the cells. The body’s organs‚ tissues and cells are run by metabolic enzymes. Without them our bodies
