    Assignment 1: Discussion Assignment Discussion Question 1 What is the difference between biochemical reactions in healthcare? Biochemical reactions occur as a chemical reaction, which naturally takes place in a living organism. It happens within a cell involving a catabolic reaction (breaking down of molecules) or a anabolic reaction (building up of molecules). The process involves a diversity of biomolecules interacting with one another in order to make up a new biochemical for a particular…

    Abstract: An enzyme, a protein, is a catalyst, which increases the rate of the chemical reaction. The results of this experiment showed how different temperatures could affect the chemical reaction between the enzyme and the hydrogen peroxide. The temperatures tested in this lab were 30, 35,40,45 Celsius, which are close to the average body temperature which is 37 Celsius. Catalase is an enzyme which breaks down hydrogen peroxide into oxygen and water. Different temperatures were measured to see…

    Reviewing my data table and graph results it is clear to see that as the substrate concentration increases so does the rate of reaction. The catalysing of enzymes involves molecular movement of the substrate and enzymes in an aqueous solution. Therefore the substrate and enzymes are moving randomly within the solution (Brownian motion). By increasing the concentration of the substrate particles the rate of reaction is increased as the substrate is much more likely to find an active site. This…

    Many factors can affect how fast an enzyme is able to change the state of a solution. Enzymes are proteins that act as catalysts, they allow reactions to be sped up by allowing the reaction to occur with a lower activation energy. Normally for a reaction to occur the molecules of each substance must collide with each other with enough energy to start the reaction. Enzymes function to remove this part of the process and interact with both substrates. Invertase is an important example of such an…

    The main objective of this lab was to observe the effect of the enzyme concentration versus the reaction time of an enzymatic reaction, and the effects of the reactants and products concentration direction of the reaction. Specifically, in this lab the enzymes salivary amylase and phosphorylase were looked at the effect of the enzyme concentration versus the reaction time of an enzymatic reaction were observed by the iodine test along with the benedict’s test. Enzymes are known as biological…

    Purpose: To test the effect of inorganic and organic catalyst concentration and surface area on the reaction rate. Introduction: In this experiment the experimenters will seek to determine what factors determine the rate of a reaction with a catalyst. A catalyst is a molecule that starts a chemical reaction, but it is not part of the reaction it is causing. The experimenters will use pieces cut up potato as an organic catalyst. The potato contain enzymes that will perform the reactions.…

    Enzymes are biological molecules (typically proteins) that significantly speed up the rate of virtually all of the chemical reactions that take place within cells. They are vital for life and serve a wide range of important functions in the body, such as aiding in digestion and metabolism. Some enzymes help break large molecules into smaller pieces that are more easily absorbed by the body. Other enzymes help bind two molecules together to produce a new molecule. Enzymes are highly selective…

    Enzymes Two major factors influence how effective an enzyme is by promoting the rate of reaction. Each enzyme has a specific temperature that allows it to perform the most work. If an enzyme is placed in an environment under its optimal functioning temperature, the speed of the reaction will slow. Reason being, the molecules of the reactants reduce in energy from the low temperature, less movement means less reactions with the enzymes. At higher temperatures, molecules within an enzyme increase…

    Background: A catalyst is a substance that increases the rate of a chemical reaction without itself undergoing permanent chemical change. The most common catalysts in biological systems are special proteins called enzymes. Enzymes are long chains of amino acids that have taken a very specific three-dimensional shape called a globular shape. This specific shape contains an area that is designed to match a specific molecule. The substance that an enzyme operates on is known as its substrate.…

    The Effects of Competitive Inhibitors on Catechol Oxidase Enzyme Activity. Jaley Willingham, 2015, Functional Biology, Texas State University, San Marcos, 78666. Abstract Competitive inhibitors may have an effect on enzyme activity. We investigated the effects that parahydroxybenzoic acid has on the enzyme activity of catechol oxidase. For this experiment, different levels of parahydroxybenzoic acid concentration were added to catechol oxidase. Each level of concentration was then tested for…
