Enzyme

Enzyme Lab “Enzymes are catalysts that speed up chemical reactions without being used up in the process” (Leady). A catalyst helps speed up a chemical reaction without being changed during the reaction. Enzymes are specific meaning that they can work with only a specific set of chemical reactions. Most enzyme names end in -ase. The shape of a protein is very important in its function for the reaction. The molecule the enzyme works on is called a substrate. In order for this enzyme to work on this

Introduction: An enzyme is a macromolecule that works as a catalyst and speeds up chemical reactions through a substrate that binds to the active site of the enzyme. When this process occurs, the enzyme lowers the activation energy needed. This allows the reactant molecules to reach a state where they can complete a reaction in most temperatures. The enzyme is not consumed when a chemical reaction is taking place, however, it’s shape changes in order to create a proper space for a substrate to bind

Background: Enzymes are proteins with specific 3D conformations, or shapes, which allow them to interact with specifically shaped substrates in an active site region. The function of enzymes is to speed up, or catalyze, reactions by lowering the activation energy (EA). The two types of enzymes are catabolic and anabolic; the former assists in breaking down substrate, while the latter assists in building up, or combining, substrates. At the molecular level, substrates must collide with enzymes with enough

biological catalysts called enzymes.” Enzymes are proteins that decrease the activation energy of the reactions, thus increasing the rate of their process. It is important to know that these type of proteins are specific to each substrate that it binds to, forming the enzyme-substrate complex. However, enzymes are influences by several factors, such as pH, substrate concentration, salt concentration, and temperature, therefore depending on the part of the body, each enzyme will react differently. For

materials quicker, cells rely on enzymes, biological catalysts, to speed up these reactions without being consumed. (General Biology I, Martineau, Dean, Gilliland, & Soderstrom, Lab Manual, 2017, 43). To produce these materials quicker, the activation reaction much be lowered, a very important part of this lab. Each enzyme acts on a specific molecule, or set of molecules, called a substrate (43). The enzyme binds to this substrate, forming an enzyme-substrate complex. An enzyme is a protein whose structure

Introduction (5 marks) Enzymes are globular shaped proteins that are found throughout the body, with their main function being to act as biological catalysts. An enzyme can act to speed up or regulate the rate of the reaction, in order to maintain an efficient rate of biological reactions. Enzymes, whilst having an important role in the reaction of many chemicals within the body, are not consumed in the reaction, and so are able to catalyze many reactions in their life cycle. Enzymes are able to reduce

Enzymes in detergent 1) What enzymes are used to make this product? There are essentially six main enzymes involved in detergent, specifically amylases, proteases, lipases, pectinases, cellulases, and mannanases. Each of these enzymes are responsible for targeting stains containing specific macromolecules like carbohydrates, proteins, and lipids. 2) What type of reactions do the enzymes catalyze, and why is this of value? Amylases are typically responsible for catalysing the breakdown of starches

Enzymes Ally Wormaan 11/07/2013 Section 018 Introduction: Our body has many cells, cells which operate like a chemical factory. Chemicals are broken down for things like energy, and new chemicals are then synthesized. The food we eat only supplies us with some of the compounds that are needed for our body to operate. Most that are needed are synthesized within the cell by hundreds of different types of reactions that are all part of metabolism. All of these reactions wouldn’t be able to take

Introduction: Enzymes defined as biological catalysts that speed the chemical reaction by reducing the activation energy (Biology Department, 2014). Enzymes play an important biological role in the cell, as it is important to keep the cell alive by speed up the reaction, which explains why in absence of enzyme some reactions need long time (Richard & Mark, 2001). Also, enzymes regulate organism intercellular function for example enzymes help to keep human body healthy by defend it from infection

1a. Enzymes are proteins, which speed up reactions – such as a “browning” reaction. We know that an enzyme in fruits is responsible for making them “brown” after being cut. We also know that the fruits do not “brown” prior to being cut. A reason that the fruits don’t brown before being cut could be that something in the air triggers the “browning” enzyme in the fruit. Therefore, when the fruit is cut, it is possible that the huge increase of oxygen from the air could trigger the “browning” enzyme
