Enzymes are components in a chemical reaction which speed up the reaction. Enzymes are similar to catalysts in the fact that they are part of the reaction. However, unlike catalysts, enzymes do not change permanently in the reaction and they do not become charged (Enzymes). The fact that enzymes are not changed during a reaction means they can be used repeatedly. When it comes to reactions, enzymes are specific about which chemical reactions they will assist. Each enzyme has a part called the active site. The active site of an enzyme is where the reacting molecules, called substrates, attach during the reaction. Each enzyme has a specially shaped active site and for this reason enzymes are specific to a reaction. If the conditions, such as

The enzymeʼs have an active site that allows only certain substances to bind, they do this by having an enzyme and substrate that fit together perfectly. If the enzyme shape is changed then the binding

The substrates bind to a region on the enzyme called the active site. The active site is precisely shaped to hold specific substrates. Beta-galactosidase is one of the three genes in the lac operon. A lac operon is an operon required for the digestion of lactose in bacteria cells. B-galactosidase converts lactose, a disaccharide, into glucose and galactose, monosaccharides.

Introduction: Enzymes are biological catalysts that increase the rate of a reaction without being chemically changed. Enzymes are globular proteins that contain an active site. A specific substrate binds to the active site of the enzyme chemically and structurally (4). Enzymes also increase the rate of a reaction by decreasing the activation energy for that reaction which is the minimum energy required for the reaction to take place (3). Multiple factors affect the activity of an enzyme (1).

If the substrate fits perfectly into the active site, then the reaction will take place, and those substrates that fit into the active site will also be known as reactants (Clark, 2007). The enzymes increase the rate of reaction, while they also lower the

An enzyme is a biomolecule that acts as a catalyst in biochemical reactions (1). Enzymes are commonly used in many products and medications. Enzymes function by flexibly binding to active sites in substrates (reactants). This binding is weak non-covalent interactions.

An enzyme is a biological catalyst (protein) which speeds up the rate of chemical reactions without changing the chemical reaction at the end. A chemical reaction is when a substance is changed into a different substance. To begin a reaction, you need energy which in this case is called activation energy. A reaction in a chemical reaction is called a substrate when it is being acted upon by an enzyme that speeds up the rate of a reaction. In addition, the region on the enzyme where the substrate binds is the active site.

Enzymes are homogeneous biological catalyst that work by lowering the activation of a reaction pathway or providing a new pathway with a low activation energy. Enzymes are special biological polymers that contain an active site, which is responsible for binding the substrates, the reactants, and processing them into products. As is true of any catalyst, the active site returns to its original state after the products are released. Many enzymes consist primarily of proteins, some featuring organic or inorganic cofactors in their active sites. However, certain ribonucleic acid (RNA) molecules can also be biological catalysts, forming ribozymes.

They can only quicken reactions that will eventually occur, but this enables the cell to have a productive metabolism, routing chemicals through metabolic pathways. Enzymes are very specific for the reactions they catalyze; they make sure the chemical processes go in the cell at any given time. Peroxidase was the enzyme being testing in this experiment. A peroxidase is an enzyme that acts as catalysts, which occurs in biological systems. Peroxidase is found in plants, which they play a role in helping to minimize damage caused by stress factors or insect pests.

The active site is the place where the substrate will attach to an enzyme and catalyse chemical reactions. The lock and key mechanism suggests that when the right substrate enters the active site, the chemical reaction will occur more quickly because the substrate will fit perfectly into

1.Introduction: An enzyme is a large protein that acts as a biological catalyst which changes the rate of a reaction. It provides an active site which is an environment where a reaction can take place this is made up of amino acids. The structure and shape of the substrate, the structure and shape of an enzyme and the substance upon which the enzyme works all have to match exactly. This enables the substrate to bind, but it can 't do this if the shapes of the two are different. The Aim of Enzyme Catalase Experiment is making a series of experiments involving the enzyme Catalase which has been performed in order to determine some of the enzyme 's properties.

They are not usually very selective. In contrast enzymes are usually very highly selective and they catalyze specific reactions only. This specificity is due to the different shapes of the enzyme molecules. Enzymes' specificity is mainly due to their unique three-dimensional structures. Like all other catalysts, enzymes also increase the rate of reaction by lowering the activation energy of the reaction.

The spot where these substrate atoms fit is known as the active site (BBC News. 2014).With the active site; it determines the shape, charge and whether the enzyme is hydrophobic or hydrophilic. On the off chance that the protein's state changes, its active site might not work. This means that the chemical has been denatured (BBC News. 2014).They can be denatured by high temperatures or extremes of pH. When there are changes in the pH or temperature, it can modify the shape of an enzyme which causes the reaction to slow down.

Enzymes are globular proteins folded into a complex 3-dimensional shape that contain a special surface region called the active site where specific substrate can bind structurally and chemically. They act as catalysts, meaning that they are substances which lower the activation energy required for a chemical reaction to occur and therefore increases the rate of the reaction. Activation Energy is the minimum energy barrier needed to be overcome before a reaction can occur by providing an alternative reaction pathway.

Introduction: Enzymes are proteins that function as catalysts, meaning that they increase the speed of a reaction without being changed themselves. The enzyme has two main jobs in a reaction that cause the reaction to increase. The first job is to bring substrates (the substances that the enzyme will be reacting on that bind to the active site in the beginning a reaction) together in an orderly fashion so that they can interact during the reaction. It’s second job is to decrease the energy needed for a reaction to take place. These tasks can be completed more efficiently in specific temperatures or with specific pH levels.
