Enzymes Enzymes are central to every biochemical process that occurs in the body. Most enzymes are proteins . There are exceptions, however. For example, there are catalytic ribonucleic acid (RNA) molecules called ribozymes that are involved in RNA processing, and, in 1994, the first DNA enzyme was engineered.

- Enzymes are biological catalysts-catalysts are substances that increase the rate of chemical reactions without being used up. Enzymes are also proteins proteins: organic compounds made up of amino acid molecules.hanges in pH alter an enzyme’s shape. Different enzymes work best at different pH values. The optimum pH for an enzyme depends on where it normally works. For example, intestinal enzymes have an optimum pH of about 7.5. Enzymes in the stomach have an optimum pH of about 2.

The Activity of the Lactase Enzyme Lactase is an enzyme produced by the human body that is responsible for breaking down lactose -- a sugar found in milk.When the body is very young, it produces elevated levels of the enzyme to help break down a steady diet of milk. As it grows older, the body gradually decreases the amount of lactase it produces.actase is an enzyme produced by the human body that is responsible for breaking down lactose -- a sugar found in milk.

- Enzymes are proteins that act as catalysts for reactions, such as those in cellular respiration. They increase the likelihood of a reaction by lowering the energy required for a reaction to occur. In the process, enzymes are left unchanged by the reaction. They may stress bonds in a molecule and increase the chance of that bond breaking and they may force molecules or atoms together and help in the formation of a new bond. The molecules that bind to the enzyme are called substrates.

Enzyme Enzymes accelerate, or catalyze, chemical reactions. The molecules at the beginning of the process are called substrates and the enzyme converts these into different molecules, called products. Almost all metabolic processes in the cell need enzymes in order to occur at rates fast enough to sustain life.f an enzyme produces too much of one substance in the organism, that substance may act as an inhibitor for the enzyme at the beginning of the pathway that produces it, causing production of the substance to slow down or stop when there is sufficient amount. This is a form of negative feedback.

- Enzymes are biological catalysts. They play a major role in metabolic pathways by lowering the activation energy necessary for chemical reactions to occur. Enzymes are generally named based on the type of substrate they act upon, followed by the suffix-ase. The primary structure of any enzyme is composed of protein.

Enzyme structure and function Enzymes are biological catalysts. Enzymes are the catalysts involved in biological chemical reactions. They are the “gnomes” inside each one of us that take molecules like nucleotides and align them together to create DNA, or amino acids to make proteins, to name two of thousands of such functions. They are so important for life that scientists weren’t satisfied with calling them catalysts, and had to invent the fancy new name “enzyme” instead. Why enzymes are so important The big reason enzymes are important to life is because cellular energy is a precious resource.

Introduction Enzymes perform the critical task of lowering a reaction's activation energy—that is, the amount of energy that must be put in for the reaction to begin. Enzymes work by binding to reactant molecules and holding them in such a way that the chemical bond-breaking and bond-forming processes take place more readily. Reaction coordinate diagram showing the course of a reaction with and without a catalyst.

- Enzymes are composed of two parts, a protein portion called the apoenzyme and a nonprotein portion, either a coenzyme (organic) or cofactor (inorganic). Enzymes are present in every cell in both plants and animals; and are responsible for regulating the biochemical reactions necessary to sustain life.he enzymes involved in food decomposition and in the digestive process are hydrolases. They break down proteins (proteases), carbohydrates (carbohydrases or amylases), and fats (lipases).

enzyme An important element in human chemistry, an enzyme is a protein manufactured by a cell, and is a catalyst in various biological functions. For example, enzymes help break down larger molecules of starch, fat, and protein during digestion. The word enzyme was coined by a German physiologist in the late 1800's to name a digestive process that scientists had been observing.

- The enzyme is not altered by the reaction. You have hundreds of different enzymes in each of your cells. Each of these enzymes is responsible for one particular reaction that occurs in the cell. In this lab, you will study an enzyme that is found in the cells of many living tissues. The name of the enzyme is catalase (KAT-uh-LAYSS); it speeds up a reaction which breaks down hydrogen peroxide, a toxic chemical, into 2 harmless substances--water and oxygen.

How are enzymes made in a cell? That is all that DNA does. The 4 million bases in an E. coli cell's DNA tell the cell how to make the 1,000 or so enzymes that an E. coli cell needs to live its life. A gene is simply a section of DNA that acts as a template to form an enzyme. Let's look at the entire process of how DNA is turned into an enzyme so you can understand how it works.

Enzymes Enzymes are large biomolecules that are responsible for many chemical reactions that are necessary to sustain life. Enzyme is a protein molecule and are biological catalysts. Enzymes increase the rate of the reaction. Enzymes are specific, they function with only one reactant to produce specific products.nzymes are highly selective, they catalyze specific reactions only. Enzymes have a part of a molecule where it just has the shape where only certain kind of substrate can bind to it, this site of activity is known as the 'active site'. The molecules that react and bind to the enzyme is known as the 'substrate'.

What are the monomers that make enzymes? Best Answer: Amino Acids are the monomers that make up protein.... and enzymes are a type of protein. (i.e. the peptide chain is the polymer made of amino acid monomers). There may be a-helixes and b-sheets formed (secondary structure). This chain then folds (into tertiary).

Enzymes and Their Dynamic Role in the Cell Enzymes are special molecules (mostly proteins) that are made in the cell and help other molecules undergo chemical reactions when they come in contact with each other. When these reactions occur, energy is either released or used up, and different molecules are produced.

Enzymes Enzymes. An enzyme is a protein that functions as a biological catalyst – a substance that speeds up a chemical reaction without being changed by the reaction. Lock and key model . Enzymes are folded into complex shapes that allow smaller molecules to fit into them. The place where these molecules fit is called the active site.

- Part I: Proteins. Proteins are made of subunits called amino acids and are used to build cells and do much of the work inside organisms. They also act as enzymes helping to control metabolic reactions in organisms. Amino acids contain two functional groups, the carboxyl group (-COOH) and the amino group (-NH2).

How Cells Work Enzymes are made from amino acids, and they are proteins. When an enzyme is formed, it is made by stringing together between 100 and 1,000 amino acids in a very specific and unique order. The chain of amino acids then folds into a unique shape.nzymes have extremely interesting properties that make them little chemical-reaction machines. The purpose of an enzyme in a cell is to allow the cell to carry out chemical reactions very quickly. These reactions allow the cell to build things or take things apart as needed. This is how a cell grows and reproduces.
