Download file to see previous pages As stated by Onteh et al (2005), most biochemical reactions would be very slow without enzymes since enzymes increase the rate of biochemical reactions by thousands times. It is therefore important to study the environmental factors: pH and temperature and how they would affect specific enzymes.
There are three characteristics of enzymes that make them function as catalysts. First enzymes increase the rate of biochemical reaction, second, they are specific to a substrate and thirdly they can be regulated to increase or reduce rate of biochemical reaction. Studies have confirmed that enzymatic activities are affected by certain factors such as enzyme concentration, pH, and temperature as well as substrate concentration. According to (), all these factors except substrate concentration have the effect of modifying the specificity nature of the enzyme there by making it incompatible with the substrate. Moreover enzymes act as catalysts because they exhibit three dimensional protein structures. As stated by Onteh et al (2005), this structure is particularly sensitive to changes in salts, pH and temperature thus a slight changes in temperatures of reaction can significantly change the rte of reaction while extreme temperatures can irreversibly alter the both the three dimensional structure of the enzyme thus making it impossible to catalyze a reaction.
The enzymatic activity is based on the fact that enzymes are made up of certain active sites that are specific to the substrate’s active sites. As stated by Onteh et al (2005), it is on this active sites that enzymes bind to a given substrate in a geometrical fashion after which substrate undergo its inherent reaction at a much faster rate. This mode of enzymatic action is referred to as lock and key. It is important to note that enzyme does not actually react with a substrate, but brings and aligns the substrate in order for it to react with other substances. Enzymes therefore have ...Download file to see next pagesRead More

Enzymes

...?Enzymes as a Catalyst There are many important organic reactions, which govern both the biological and physiological world. Within our body, hundreds of chemical processes occur simultaneously under a variety of conditions. Many of these processes are interconnected, meaning that there are biochemical pathways, which require the activation of multiple enzymes in order to achieve a desired biological product. Enzymes are biological molecules that are not consumed in a reaction and are special biological molecules, which are encoded for and activated, in the appropriate biological settings. Enzymes are a specific kind of protein that is used to catalyze biological...

Enzymes

...?Enzymes: What ?They Do, Why They Are Important Enzymes are the cornerstone of life in every being. It is a type of cell that is found in every man, animal, plant, and other life forms. Amino acids of various shapes and sizes, often numbering anywhere from 100 to 100,000 form the basis of enzymes which are considered to be proteins. The amino acid chain carries a unique shape which is tailor made to help the chemical reaction necessary for the amino acid to perform a specific action. Enzymes can therefore be considered to be catalysts for specific actions or reactions such as in the case of food digestion. These enzyme reactions are chemical processes...

Enzymes in Industry

...The workings of life, from digestion to replication, synthesis of nucleic acids to the destruction of bacterial cell walls, from defense to duplication, depend to a very great extent on enzymes. Not only within the framework of our bodies but also now in industrial applications of various sorts have we become dependent on these tiny proteins. Humans have been utilizing enzymes from the first time they made wine and baked bread or made cheese, though unwittingly. The discovery of and recognition of enzymes as such took man a very long time considering how early he began to use them for his purposes. It is the aim of this paper to discuss the workings and history of enzymes...

Enzymes

...The human body carries out many metabolic activities to maintain homeostasis as well as provide energy for that given body. To catalyze this energy and organic necessities to uphold the constructs of the body, enzymes are engendered to establish such feats in the body. Enzymes are proliferated out of the sequencing of the amino acids accordingly. Each type of enzyme has a different type arrangement, and therefore, each possess a specific function. In this dissertation, we will examine and discuss the function of enzymes and its proliferation. Then we will utilize acquired information to examine a given experiment. Scientists have explored the concepts of the...

Lactate & Enzymes

...Lactate & Enzymes Under what conditions, and why is lactate produced in the body Occurring naturally, lactate is a compound formed in the body. These are by-products of and energy for exercise: which is commonly found in the muscles, the blood and various organs. The primary source of lactate is the breakdown of stored carbohydrate called glycogen. Glycogen breaks down into a substance called pyruvate and, in the process, produces energy. We often refer to this process as anaerobic energy because it does not use any oxygen. When pyruvate breaks down further, it produces much more energy. This energy is called aerobic because this process uses oxygen. If pyruvate does not break down, it usually turns into lactate. When...

Enzymes

...Enzymes In the most basic sense, enzymes are the proteins that facilitate in accelerating the different chemical reactions. The molecules which are present in these enzymes at the starting are known as the substrates and it is from this state that the enzymes begin to convert into a number of distinct molecular products. The different processes which are going on within a cell require the usage of different enzymes. The enzymes speed up the chemical reactions in only a selected portion of the substrates. The metabolic reactions and the unique pathways which are adjoined with it are present within a cell nonetheless....

Macromolecules and Enzymes

...This study was carried out to identify the different types of macromolecules and to learn about its respective properties. Since no singlestudy can lead to identification of carbohydrates, two tests 1) Benedicts reagent was done to identify monosaccharide, glucose and ribose; 2) Lugol`s iodine was used for the identification of starch, a polysaccharide. Visual observation of simply adding few drops of salad oil in water shows that oil is less dense than water and is immiscible. Enzyme reaction and specificity was studied using the enzymes Tyrosinase and Sucrase. Effect of different physical parameters including temperature, enzyme concentration and pH was determined for the...

Enzymes

...Enzymes increase the rate of chemical reaction by inducing the reaction to proceed to a path with a lower activation energy. For example, the catalyzed dissociation of a compound is hastened by exposing it to a positively charged catalyst, which attracts the anionic component of the reactant, and subsequently weakens the ionic bond between them. As a result, a lower energy is needed to completely break the bond between the compound (Masterton and Hurley, 2005, p. 303-304). Despite its effectiveness, enzymes only work within a narrow range of conditions. Because they are usually proteins, a temperature lower or higher than the optimal range results to denaturation, which changes the shape of the protein....

Enzymes activity

...Lab report: Enzyme kinetics of inhibition al affiliation Background information: Enzyme catalyze reactions in the humanbody by converting substrates into products. They increase the reaction rate by lowering the activation energy thereforereaching the steady state more rapidly. Enzyme activity is affected by temperature, pH and substrate concentration. Inhibitors also affect working of enzyme by competitively, non-competitively and mixed reaction. Method: a calibration graph that had been previously prepared was used. A Line-weaver Burk was plotted with reciprocal of substrate plotted against reciprocal of reaction rate was made to determine Vmax and Km values of three...
