Enzyme catalysis

oxygen produced, also changed accordingly. This enzyme controlled reaction will be fastest at a particular pH – the optimum for the enzyme and slower at pH values above and below the optimum. The values from my experiment clearly show that when the pH of the reaction mixture was increased towards or decreased from the optimum pH of the enzyme the rate of the reaction subsequently increased or decreased. My results visibly show that the optimum for this enzyme is pH 7, the pH at which the highest rate of

Enzymes are globular proteins that act as catalysts which affect the rate of chemical reaction without being destroyed or altered during the process. They are very effective in the body systems of organisms, an enzyme that catalyzes more than one thousand chemical reactions per second. But there are certain conditions that enzymes can work normally or efficiently, such as the temperature of the environment must be correct for each enzyme because different enzymes will have different optimum temperature

was done to investigate the effects of low pH on enzymes activities. According to Dunaway, Mariano, D. (2008) enzymes are protein in nature. They are used to speed up the rate of reactions. At, the end of the experiment, enzyme is not used up. There are several factors that affect the rate of enzymatic activities. Some of them include temperatures, pH and amount of reagent. In our experiment, we decided to carry a test on the effects of low pH on enzyme activities. The objectives of the experiment

Introduction An enzyme is a protein that acts as a catalyst which reduces the activation energy needed for a chemical reaction. Without the presence of enzyme, cell reactions would take so long that they would detectable. During a reaction, in the presence of an enzyme, the substrate first creates a complex with the enzyme. While the substrate is a part of the complex, it’s converted into the product. Then, finally, the complex dissociates from the molecule which allows the release of the enzyme and formed

Enzymes play a remarkably important role in biological systems. Nearly all reactions in living organisms are catalyzed by enzymes, a large majority of which have been found to be proteins. The mechanisms by which enzymes function are varied, but all mechanisms lower the transition state free energy where the free energy barrier of a reaction is the highest. Thus, an enzymatically catalyzed reaction proceeds at a significantly increased rate than that of an unanalyzed reaction. Even though the mechanism

Enzymes are biological catalysts that are involved in important pathways that allow the chemical reaction to occur at higher rates than would be possible without the enzymes. Enzymes are globular proteins that are responsible for biochemical reactions within cells and microorganism, these large proteins have more than one substrate binding sites allowing larger volumes of products to be produced. Enzyme assays are fundamental tools for measuring cellular activity and for monitoring enzyme protein

Background Research Enzymes are tertiary and quaternary structures of proteins and biological catalysts that accelerate the rates of chemical reactions. Enzymes are significant in that they are not permanently changed in the process and may be reused. Enzymes speed up chemical reactions by lowering the activation energy needed to start a chemical reaction. The process of speeding up a chemical reaction via the use of enzymes begins when a substrate, the substance (reactant) that an enzyme acts upon, binds

Enzymes are globular proteins that catalyse chemical reactions, which results in the rate of reaction being increased. Catalysed reactions can be increased by 1020 in terms of their rate compared to non-catalysed rate of 102-4. There allosteric and non-allosteric enzymes. Allosteric enzymes have two or more binding sites that regulate each other. Non-allosteric have more than binding site, but do not regulate each other. Enzymes have specific actions. Three types of specifies exist: group specificity

of substrate concentration concentration on the rate of reaction” Introduction Enzymes catalyse biological reactions ,increasing the rate of chemical reactions Enzymes have an affect on the structure of chemical transformation (stryer et al , 2011 ) Enzyme substances bind at the active cite which contains amino acid chains. Without catalysis reactions the process would take place slowly to produce products , enzymes are most effective catalyst (Campbell and Farrell, 2011) .A catalysed reaction is

temperature, pH and enzyme concentrations affect the reaction rates of enzymes. Background Enzymes are considered to be “biological catalysts” meaning they can speed up a chemical reaction in a cell without being used up in the process. Enzymes do this by lowering the amount of energy needed to activate the process. The lower the activation energy, the faster the reaction. Without enzymes, vital life processes would occur very slowly which could be deadly. Different enzymes are used depending on
