Enzyme substrate

Introduction: Enzymes are a type of the macromolecule protein, used in metabolic reactions that occur within the cell of living organisms. The role of enzymes in these reactions is to decrease the amount of energy needed to start the reactions, thus assisting the metabolic process by increasing the speed at which the reaction occurs. In other words, enzymes allow the metabolic process to happen faster than it would naturally, making them catalysts. The structure of an enzyme is important to…

at which enzyme activity is most effective is approximately at 40℃. This result was expected as this trial temperature was closest to internal body temperature, 38℃, and as catalase is present in all body organs (T. Fouad, Antioxidants). Temperature affects chemical reactions by increasing the kinetic motion of molecules and changing the rate of collisions between them. In lower temperatures, kinetic motion is decreased and there are not enough collisions between the molecules for enzyme…

BIO LAB 1130.036 December 1, 2016 They call me DJ Enzyme because I 'm always breaking it down Abstract: Although protein function is thought to depend on the dynamics of the molecule and its environment contribute to catalytic mechanisms. The increase and decrease of temperatures affected the rate of reaction. In nature, organisms adjust the conditions of their enzymes to produce an optimum rate of reaction, where necessary, may have enzymes which are adapted to function well in extreme…

HALDANE RELATIONSHIP AND ONE-WAY ENZYMES  INTRODUCTION: Most of the enzyme catalyzed biological reactions are reversible in nature. However, an enzyme may prefer to catalyze the reaction more efficiently in one direction over the other under given physiological concentrations of substrate or product (substrate in the reverse direction). An enzyme favouring a virtual unidirectional catalysis of an overall reversible reaction can’t escape the laws of thermodynamics. As a catalyst doesn’t change…

There are factors that can affect the enzymatic activity. Enzymes are known to speed up the biological reactions. It is specific to its substrate which in this experiment is known to be catechol. The catechol oxidase is used in all parts to express the concentration in the enzyme reacting into ortho-quinone (Schultz, 2006). The catechol oxidase if from the potato that was used in this experiment. The enzyme was extracted as the full strength after centrifugation and used the homogenization as…

functioning. Enzymes are catalysts that are used to speed up these reactions. If you take for example if a person was trying to get from Point A to Point B, there are two routes; one route where you have to go over a steep hill, which would take additional time or the other route is to go around the hill and get to Point B using less time. This example is an illustration of enzyme catalyst. They are what give reactions an alternative route. They allow reactions to occur faster however, enzyme…

Introduction Enzymes are proteins that are biological catalysts that increases the rate of chemical reactions (JRank Articles). With the use of enzymes it can accelerate certain reaction rates at a faster past then if the reaction was moving at it natural speed (JRank Articles). The activity of enzymes are control by many things like environment, inhibitors, and regulatory binding sites that happens on the enzyme(JRank Articles).The overall reaction in the natural setting which was the basic…

Effects of Substrate Concentration and Temperature on a Catalase Reaction Rate Introduction Catalase is a vital component in the human body. The most crucial of which would be Enzymes, these are protein catalysts. A catalyst speeds up a chemical reaction rate. Virtually all chemical reactions within the human body require a catalase enzyme to be completed in the proper amount of time. The decomposition of hydrogen peroxide to oxygen and water can be completed with the catalase enzyme (Thompson,…

various temperatures on Enzyme activity Introduction: The basic properties of life revolve around chemical reactions. Without the presence of enzymes some of life's processes would not happen easily. An enzyme is a macromolecule serving as a catalyst, they are generally a protein based molecule, as it is in the lab, Enzymes are organic catalysts that control the rate of chemical reactions in cells while not being permanently changed or without being consumed, which makes enzymes different…

Background Research Enzymes are proteins that act as biological catalysts. A catalyst can be defined as a substance that increases the rate of a chemical reaction without itself undergoing any permanent chemical change. Enzymes are essential due to the fact that virtually every metabolic reaction which takes place within a living organism is catalyzed by an enzyme. This is because organisms catalyze the chemical reactions that would otherwise not be able to progress under typical physiological…
