Enzyme

- The purpose of this experiment is to find out what affect temperature has on enzyme activity. To find out all this we need to know what an enzyme actually is. An enzyme is an organic compound that breaks downs vitamins and nutrients into usable energy for you body, but not only does it break down it also builds up. An enzyme is also known as an organic catalyst. What is a catalyst you ask? A catalyst is a substance that increases the chemical rate of reaction. A catalyst is not used up by the

The effect of the enzyme concentration on the rate of enzyme activity is that as the enzyme concentration is increased, the rate of enzyme activity is also increased. This occurs because an enzyme is a catalyst that speeds up a chemical reaction by breaking the chemical bond in a substrate. The substrate is the reactant that is consumed in the reaction as it fits in the active sites of the enzyme. This is called the lock-and-key mechanism, where the enzyme grabs a hold of the substrate which known

Enzymes play a critical role in metabolic processes by speeding up chemical reactions. Enzymes lower energy barriers by acting as a catalyst for a reaction. An example is hydrolysis that occurs in glucose. Without enzymes glucose will still hydrolyze, but at a slow rate. With the right enzyme hydrolysis will occur even more rapidly than before. Enzymes work by having a substrates enter their active site. Induce fit (the substrates forms weak bonds with the enzyme causing the enzymes shape to enfold

Gail Francis Enzyme Lab Introduction Enzymes are organic catalysts that speed up metabolic reactions (Denniston, 2007). In short, enzyme functions by binding one or more of the reactants in a reaction. Specific enzymes only lower the activation energy for specific reactions and enzymes are shape-specific. The reactants that bind to the enzyme are known as substrates of the enzyme. The exact location on the enzyme where substrate binding takes place is called the active site of the enzyme. When substrates

Enzymes are proteins produced by living cells that act as catalysts, which affect the rate of a biochemical reaction. They allow these complex biochemical reactions to occur at a relatively low energy usage. In enzyme-catalyzed reactions, a substrate, the substance to be acted upon, binds to the active site on an enzyme to form the desired product. Each active site on the enzyme is unique to the substrate it will bind with causing each to have an individual three-dimensional structure(this is

Name of Lab: Properties of Enzymes Date: November 2015 Name of Instructor: Mr. Jeffrey Ellis Subject Section: Biology I/Lab 1500 (DAC) Abstract: In this lab or experiment, the aim was to determine the following factors of enzymes: (1) the effects of enzymes concentration the catalytic rate or the rate of the reaction, (2) the effects of pH on a particular enzyme, an enzyme known and referred throughout this experiment as ALP (alkaline phosphate enzyme) and lastly (3) the effects

MathenyBIO-182L2 February 2017Dr. FrancisIntroduction An enzyme is a catalyzes chemical reactions with in a cell. Enzyme are specific on a certain kind of substrate this is based on the structure of the active site if the enzyme, the site where the substrate reaction occurs, and the structure of the substrate. The active site binds with the substrate and creates an environment that is optimal for the substrate chemical reaction to occur. The enzyme does this by lowering the activation energy required

The purpose of Enzyme Lab is to test how enzyme react with substrate at different environment. Protein is made of one or more lone chain of amino acid that help to perform many different function inside the body, and many of the enzymes are protein. Enzyme is substance act like a catalysts, it bind with substrate lower the activation energy to increase the rate of chemical reaction of the cell. Substrate act as a key to enzyme, they will find a enzyme that could bind with them and cause reaction

different concentrations of peroxidase. This enzyme was extracted from turnip roots using a pH 7 buffer. The data that was gathered was used for further investigation on the subject. The inquiry experiment used the same enzyme from a different root, a potato. In theory, this change in enzyme should have changed the rate at which it catalyzed, which would change the rate of absorbance. In this case it did, the potato enzyme reacted much slower than the turnip enzyme. Three trials were performed with a mixture

it. This graph does not provide evidence that enzymes physically bind to their substrates. If the graph were to represent this hypothesis, it would be a linear graph. This is because each enzyme would only physically bind with two substrates at a time. Therefore, as the number of substrates increases so would the reaction rate in a 1:2 ratio, creating a linear graph. If the hypothesis was wrong and the substrates and enzymes did not physically
