    Coenzymes are small organic molecules that associate to enzyme and whose existence is necessary to the action of those enzymes. Coenzymes belong to the larger group called cofactors. several reactions of substrates are catalyzed by en¬zymes only in the presence of a definite non-protein organic molecule called the coenzyme. Coenzymes unite with the apoenzyme (the pro¬tein part) to form holoenzyme. Fig 1: coenzyme Classification of co-enzymes Coenzymes can be classified into 2 groups according to

    Enzymes Enzymes are biological catalysts. A catalyst is defined as a substance that increases the rate of a chemical reaction without itself undergoing any permanentchange. Enzymes do precisely this in living things. Without them, the rate of the reactions would be so slow as to cause serious, if not fatal, damage. Enzymes have two main functions: To act as highly specific catalysts, and also to provide a way of controlling reactions, the amount of enzyme determines how quickly the reaction

    Enzyme technology is best described as the technology associated with the application of enzymes as the tools of industry, agriculture and medicine. Although the earliest reports concerning exploitation of enzymes were documented in the late 1800’s, true industrial application on enzymes only began in earnest in the late 1960’s. The majority of enzymes used in industrial/biotechnological applications are derived from particular fungi (Aspergillus) and bacteria (bacillus). Safe organisms must be used

    Enzymes Enzymes are biological catalysts that carry out thousands of chemical reactions that occur in living cells. They are a class of proteins that have a unique three dimensional structure that allows it to bind with a specific substrate to facilitate a reaction. Many biological reactions will not occur spontaneously in the cell; there is simply not enough energy for the reaction to take place. Enzymes make these reactions possible by lowering the reactionÂ’s activation energy. Each

    Analysing Enzyme Activity under Varying Physiological Conditions Introduction and Aim Pyrophosphatase, a stable, soluble enzyme obtained by exposing cells found in tissues, is involved in a highly exergonic reaction to which it catalyses two phosphate molecules from a single pyrophosphate molecule1. Reactions that involve pyrophosphatase are effectively irreversible once a product has been created. The function of pyrophosphatase is to catalyse reactions, mainly hydrolysis within the body. Enzyme kinetics

    Enzymes Enzymes are catalysts. Most are proteins. (A few ribonucleoprotein enzymes have been discovered and, for some of these, the catalytic activity is in the RNA part rather than the protein part. Link to discussion of these ribozymes.) Enzymes bind temporarily to one or more of the reactants of the reaction they catalyze. In doing so, they lower the amount of activation energy

    Introduction: Enzymes are an important part of all metabolic reactions in the body. They are catalytic proteins, able to increase the rate of a reaction, without being consumed in the process of doing so (Campbell 96). This allows the enzyme to be used again in another reaction. Enzymes speed up reactions by lowering the activation energy, the energy needed to break the chemical bonds between reactants allowing them to combine with other substances and form products (Campbell 100). In this experiment

    Enzymes are proteins or RNA, ribonucleic acid. An enzyme speeds up a chemical reaction. Since the enzyme is not changed by speeding up a chemical reaction, the enzyme can speed up reactions again and again. In a process called catalysis, an enzyme takes what would have been a relatively slow reaction, and makes it faster than the reaction would have been without the enzyme. Enzymes also take the activation energy, which is the energy needed to start reactions, and shortens it. With the decrease in

    Enzymes Enzymes are the sparks that start the essential chemical reactions our bodies need to live. They are necessary for digesting food, for stimulating the brain, for providing cellular energy, and for repairing all tissues, organs, and cells. There are three types of enzymes: metabolic enzymes, digestive enzymes, and food enzymes. Metabolic enzymes catalyse, or spark, the reactions within the cells. The body's organs, tissues and cells are run by metabolic enzymes. Without them our bodies

    Enzymes Enzymes are complex proteins that carry out essentially every chemical reaction in the human body. Enzymes function as biological catalyst, regulating the rate at which chemical reactions proceed without themselves being altered in the process. In this particular experiment we recognized benzoquinone and examined two numbers of factors to determine their effects on enzyme action. The factors were temperature and specificity (how discriminating the enzyme is in catalyzing different
