Enzymes are necessary for a human to live a comfortable life every day. They give us the energy to move all of our muscles. An enzyme can be any of various proteins originating from living cells and that are capable of producing certain chemical changes in organic substances by catalytic action (Dictionary.com). Catalysts are a substance which lowers the amount of energy necessary for a chemical reaction to proceed and speeds up a metabolic reaction (Book). During activation energy the minimum amount for energy is being used to change a stable molecule into an active molecule. The substrate binds to the enzyme at a location called the active site just before the reaction catalyzed by the enzyme takes... View More »

This test tube also should not produce Benzoquinone because there is no potato extract with Catechol Oxidase. Also the color most likely will not go over an intensity of 1.
The second experiment 8.4 Effect of Temperature on Enzyme Activity used six test tubes all with the same 2mL potato extract with Catechol Oxidase. They need to be placed in different temperatures; 0°C, 25°C, 40°C, 60°C, 80°C, and 100°C. After 5 minutes 2mL of Catechol Solution needs to be added. After another 5 minutes we have to record each test tubes color. From knowing that optimal temperature for enzyme activity is room temperature I would come to the belief that test tube #2 being in 25°C will have the dark brown color with the intensity of 5. Test tube #1 I believe will be a shade of brown but not dark enough, maybe an intensity of 3. Test tubes #3 and #4 are close in temperature so I believe they will be around an intensity of 4 with a light brown color. Test tubes #5 and #6 I think will change color but not much so I think an intensity between 1 and 2 with a light pink or whitish color.
In the final experiment 8.5 Effect of pH on Enzyme Activity seven test tubes filled all with the same 4mL of specific buffer (pH 2, 4, 6, 7, 8, 10, and 12) and 2 mL of potato extract with Catechol Oxidase. We have to record the original color then place each in 40°C water for 5 mins. After that we need to add 2mL of Catechol Solution and then place them back in the same 40°C water for another 5 minutes. From knowing that a pH of 7 is optimal in life I would think that test tube #4, containing the pH of ...

    1)Enzymes are our body's workers. Their jobs are: constructing, synthesizing, carrying, dispensing, delivering, and eliminating the ingredients and chemicals our body uses in its daily life. Enzymes are required for your body to function properly because without enzymes we wouldn't be able to breathe, swallow, drink, eat, or digest our food. To do all of these things, our body needs some help. You must have enzymes to help perform these tasks. Enzymes are a necessity to life. Enzymes are proteins made up of long chains of amino acids, these enzymes are biological catalysts, their job is to sp

    Enzyme action A chemical reaction occurs only if there is sufficient energy to begin the reaction. In the absence of enzymes, this energy requirement is high. Enzymes reduce the amount of energy required to begin the reactions they catalyse (see figure 3.8). Hence, enzymes increase the rate of the reactions that occur in living organisms. Without enzymes, metabolism would be so slow at body temperature that insufficient energy would be available to maintain life. FIGURE: Enzymes reduce the amount of energy required to begin the reactions they catalyse. Note the diff

    ENZYME STRUCTURE Enzymes are very important molecules. They are globular proteins that help speed up chemical reactions in the body without being changed structurally. Enzymes can be reused continually to form new products. To understand enzymes, we’ll first look at the general structure of proteins and the importance of enzyme functions in our bodies. Protein Structure Proteins are a major class of macromolecules found in all living organisms. Proteins are vital for growth and are found in the major tissues of the body such as muscle, cartilage and bones.

    The Effect Of Ph On Enzyme Activity

    The Effect of pH on Function of Catecholase Enzyme in Potato Abstract In biochemical reactions, enzymes activity could be changed based on these factors: concentration of substrates, salt concentration, allosteric regulators, temperature and pH. Inventing the hypothesis is increasing concentration of pH would increase the activity of enzyme Catecholase and the rate of reaction. Therefore, the purpose of this experiment was to test the effect of pH on Catecholase (one kind of enzymes in potato) activity by using pH12 buffer. By using the Spectronic 20D+ Spectrophotometer, the change

    Introduction Proteases Enzymes are used in chemical industries and other industrial applications when extremely specific catalysts are required. Proteases, the enzymes that cleave other proteins or even themselves in catalytic fashion, are of immense importance from a biological and also industrial point of view. They make up the largest single family of enzymes, constituting an estimated 2% of the human genome. Proteases are classified into six groups: aspartate, cysteine, glutamate, metallo, serine, and threonine based on characteristic mechanistic features. De

    Transgenesis Recombinant DNA: Recombining DNA is a way of modifying genes using restriction enzymes and ligation. Restriction enzymes are enzymes which are able to cut DNA at certain spots called recognition sites. These recognition sites allow us to cut DNA into fragments which are exactly the length we require. Once cut, they DNA fragments will have either sticky or blunt ends. The sticky ends produced are then made into blunt ends using enzymes which digest single strand DNA. Using restriction enzymes, we end up with a fragment of DNA which can then be used to re

    There are two types of cells in the salivary glands which make either mucous or serous secretions. Salivary glands make are there to create saliva. Saliva is made up of 99.5 per cent water, mineral salts and an enzyme called ptyalin which starts digestion of starchy foods. Saliva keeps parts of the digestive system wet and assists in keeping the food slippery and so it is easier chewed and swallowed. It also helps break down carbohydrates. It is controlled by the autonomic system but is stimulated by hunger, and by the sight and smell of food. There are three main sal

    Enzymes are substances that are formed by living organisms; they act as a catalyst to bring forth a specific biochemical reaction. Not only do they speed up reactions and remain unchanged at the end of the reaction but they also reduce activation energy. One of the most fascinating things about enzymes is that they are very unique having mentioned that, each enzyme has a function, a specific function. Active sites are possessed by every single enzyme, this active site is a section which is open and only allows the right substrate to bind with its molecules. Substrate interaction with the activ
