    one of the factors that affect the enzyme activity will be examined. All enzymes are proteins. The function of enzymes are to accelerate defined chemical reactions by alternating the rate of the reaction. They will not trigger a reaction to take place that would not occur naturally. Having a particular enzyme to catalyze each of the chemical reactions that take place in a living cell, total control of metabolism can be sustained by an organism. Catalase is an enzyme found in cellular organelles called

    Enzyme Reactions and Temperature Purpose Aim - To determine the effect of temperature on the rate of reaction of rennin when it reacts with milk to cause coagulation. Hypothesis - As rennin is naturally found in the human stomach I believe that the optimal temperature for reaction will be approximately 37°C as this is the regular human body temperature. This is shown by the graph below. [IMAGE][1] Background Research Rennin is "an enzyme that catalyses the coagulation of milk

    effect of enzyme age on rate of reaction Research Question: What is the effect of the age of the enzyme catalase on rate of decomposition of hydrogen peroxide? Introduction Any substance which speeds up the rate of a chemical reaction without being consumed or permanently changed is called a catalyst. Catalysts made by living organisms are called enzymes. Enzymes can be used to speed up metabolic reactions, digest food, and break down toxins in the body (Williams). Catalase is an enzyme which catalyzes

    Rate of Reaction Using Enzymes In this bit of coursework I will be investigating the rate of reaction in which enzymes are the catalyst breaking down a substrate. The substrate I am going to use is Hydrogen Peroxide (H2O2, water with another Oxygen), this molecule usually breaks down on its own accord, but also the rate of decomposition can be increased with the use of a catalyst; in this case the catalyst is a biological one called an enzyme. Hydrogen Peroxide slowly breaks down on its

    rate of reaction of the enzyme? Background information: Catalysis is the increase in the rates of chemical reactions due to the participation of catalysts. Catalysts are substances that cause catalysis. An example of this is enzymes. Enzymes are proteins that speed up the rate of a chemical reaction of substrates. The substrates will be broken down or turn into products with the aid of enzymes. Enzymes and substrates are often said to fit like a “lock and key model” because each enzyme has exactly

    How Temperature Affects Enzyme Reactions I am planning to perform an experiment to find out how and if temperature affects the rate of which enzyme reacts. The enzyme I will be using will be amylase. Amylase is an enzyme that breaks down starch so we will test at what temperature the amylase will break down the starch at the quickest time, therefore looking for the enzymes’ optimum temperature, at a temperature lower than the unknown optimum the amylase will work slower meaning more time

    the Progress of an Enzyme Controlled Reaction Plan ---- Enzymes are a widely used source of biological catalyst; they are used in widely in industry as in the biological aspects. Enzymes are biological catalyst; this means that they will speed up a reaction with out becoming used up. The enzymes for this by not actually interfering with the reaction its self but basically align the two substrates on the active site of the enzyme. Amylases are widely spread enzymes that hydrolyse starch

    Investigating Enzyme Substrate Reactions Aim: To devise an experiment which will give greater understanding about enzyme catalysed reactions. Background Information Hydrogen peroxide (H2O2) is a powerful oxidant; it readily breaks down into water and oxygen. The breakdown can be speeded up by introducing the enzyme, oxidoreductase (commonly known as catalase). [IMAGE] I will investigate the effect of varying hydrogen peroxide concentrations on the rate of reaction. Prediction

    quantity of enzymes and the rate of reaction with the substrate? Hypothesis Using my scientific knowledge my hypothesis is that as the quantity of enzymes increases so will the rate of reaction. Reasons for this hypothesis I am basing my hypothesis on a hypothesis known as the ‘lock and key hypothesis.’ It explains that when an enzyme substrate complex forms by means of a spontaneous reaction the substrate fits into the active site like a key fits a lock. It is known as a spontaneous reaction not because
