    Introduction Enzymes, which speed up a chemical reaction without being consumed or changing the products of the reaction, are very important because they control the cellular activity of all living organisms. Enzymes are also described as being “catalysts”. In biological systems, specific enzymes catalyze particular cellular reactions. Each enzyme has a unique 3-D shape, and this shape determines which reaction it catalyzes. However, in order for a chemical reaction to move forward, an energy…

    Research Question: How do different concentrations of nitric acid (measured in molars) with copper powder (grams) affect the rate of reaction (measured in seconds) measured using a stopwatch? Hypothesis: The copper powder placed in the most concentrated amount of nitric acid, measured in molar, will take the least amount of time, measured in seconds, to react compared to the amounts of copper powder in other less concentrated amounts of nitric acid. This is as if the concentration of nitric acid…

    Research Question How does the increase of concentrated hydrochloric acid affect the rate of the chemical reaction with sodium thiosulphate? Background to the Research question Chemical reaction involves the chemical change of atoms and molecules, it will occur when two or more molecules interact with each other and the molecule will change. Thus, bonds between atoms are broken down and then new molecules are formed. Hydrochloric Acid and Sodium thiosulfate are both colourless and clear…

    Enzymes

    help catalyze numerous reactions in the body. They are an arrangement of proteins designed to serve very specific roles. Enzymes contain active sites that substrates bind to. The enzymes then help orient those substrates so they achieve ideal reaction conditions. As a result, substrates are broken down much faster than they would on their own (Lawless 2016). Due to the fact that so many different arrangements of proteins are possible, it’s no surprise that so many reactions in the body are all…

    catalytic proteins made up of amino acids and are a key part of the breakdown and synthesis of virtually every biological catalysis reaction mechanism. The primary function of a catalytic enzyme is to increase the rate of reaction by helping the enzyme overcome the activation energy barrier without the reaction consuming or changing the enzyme. In enzymatic reactions, the substrate binds to the highly specific enzyme active site (the substrate-binding domain) and forms an enzyme-substrate…

    half of its maximum rate of reaction. (Oregon 2015) It reveals the enzymes affinity for the substrate and shows the magnitude of the enzymes affect on changing the rate of the reaction. For example, an enzyme with a high Km needs a large concentration of substrate to efficiently increase the rate of the reaction. (Oregon 2015) A low Km indicates that the enzyme will increase the rate of reaction with a small amount of substrate. Kcat is a constant that describes the turnover rate of an…

    This experiment monitored the synthesis of uridine from the deamination of cytidine through separating the contents of the reaction mixture using HPLC (High-performance liquid chromatography) at various time intervals since the start of the reaction. Cytidine and uridine standards are ran and the output of the HPLC will show two peaks based on the retention times of each compound. Identified the peak with the retention time of 2.422 minutes is cytidine and uridine has a retention time of 2.716…

    the rate of reaction on Enzyme reaction Introduction: This experiment will investigate the effect of temperature on the rate of reaction of the enzyme catalase. The biological catalyst called enzymes increase the rate of reaction without themselves being chemically changed. Enzymes are globular proteins folded into a complex 3-dimensional shape that contains a special surface area called the active site where a specific substrate binds structurally and chemically. Enzymes speed up reactions…

    As the temperature increases, the rate of reaction increases until it has reached the optimum temperature above 37°C where the temperature is very high then the reaction rate will decrease. In the data table shown above, there is a similar pattern from increasing the temperature will increase the rate of reaction and as the temperature slowly increases to a certain point then the reaction rate will decrease. When the temperature increase above 37°C, then denature will occur. Also, the…
