Effects of Temperature, pH, Enzyme Concentration, and Substrate Concentration on Enzymatic Activity INTRODUCTION Enzymes, proteins that act as catalysts, are the most important type of protein[1]. Catalysts speed up chemical reactions and can go without being used up or changed [3] Without enzymes, the biochemical reactions that take place will react too slowly to keep up with the metabolic needs and the life functions of organisms. Catecholase is a reaction between oxygen and catechol
The Effects Temperature, pH and enzyme concentration have on Enzyme Catalase Tiffany Sievers Biology 110, Community College of Baltimore County Abstract The purpose of this experiment was to test the effects that temperature, pH, and substrate concentration have on an enzyme catalase reaction. What affects will temperature, substrate concentration, and pH levels have on an enzymes catalase reaction? Temperature, pH levels and substrate concentration will have an effect on the
Introduction (5 marks) Enzymes are globular shaped proteins that are found throughout the body, with their main function being to act as biological catalysts. An enzyme can act to speed up or regulate the rate of the reaction, in order to maintain an efficient rate of biological reactions. Enzymes, whilst having an important role in the reaction of many chemicals within the body, are not consumed in the reaction, and so are able to catalyze many reactions in their life cycle. Enzymes are able to reduce
Abstract: Enzymes are specific-type proteins that act as a catalyst by lowering the activation energy of a reaction. Each enzyme binds closely to the substrate; this greatly increases the reaction rate of the bounded substrate. Amylase enzyme, just like any other enzyme, has an optimum PH and temperature range in which it is most active, and in which the substrate binds most easily. The purpose of this experiment was to determine (1) the reaction rate of an amylase enzyme in starch and (2)
Enzymes are globular proteins that are produced by any living organisms, which act as biological catalysts (Bio factsheet 2017). This means that they speed up the rate of reaction by lowering the activation energy that is the energy required to break bonds (BBC 2014). The activities of enzyme are determined by their three-dimensional structure (IHW 2005). The place where these substrate molecules fit is called the active site (Figure 1.1 below) (BBC 2014). Each Enzyme will only speed up one reaction
reaction rate of an enzyme if the temperature, pH level, concentration of a substrate and enzyme were changed. In this experiment, the enzyme catecholase, commonly found in plants, was tested and its product formation, benzoquinone was measured. When the concentration of the reactants such as the enzyme catecholase, and the substrate catechol were tested, the results of product formation increased greatly because the higher concentrations allowed the enzymes to increase their activity rates. When physical
Enzymes are an important type of protein in which proposes to speed up chemical reactions of substrate molecules. They are specific, each enzyme can only bind one substrate and control one reaction, an example of the following is maltase which works on only one maltose, they can be used multiple times. Each enzyme has an optimum temperature, below the temperature the enzyme will work slowly or become inactive, on the other hand, above the temperature the enzyme is denatured. In addition, each enzyme
#1 1. At substrate concentration, the enzyme is working at “maximum efficiency.” With a concentration at 40, it produced 2,339 products. 2. The maximum velocity of a reaction is reached when the active sites are almost continuously filled. Increased substrate concentration after this point will not increase the rate. The reaction rate increases as substrate concentration is increased. It will soon level off though. 3. When the concentration is at low substrate, most of the enzyme molecules
Introduction: An enzyme is a protein-based molecule, which acts as a catalyst (a catalyst is a biological molecule which serves to increase the rate at which a chemical reaction occurs by lowering the activation energy barrier without being consumed). The purpose of this experiment was to determine the properties of acid phosphatase (APase) a wheat-germ based enzyme, whose optimal conditions are as follows: pH of 4.8 and temperature of 37 oC) (acid phosphatases remove phosphate groups from molecules
Enzymes are one of an important function to the body. An enzyme is a catalyst that speeds up chemical reactions without being used up in the process (Leady 2017). In simpler terms, it is a substance that is used for chemical reactions to accelerate the chemical reaction, and create a new product from the previous substance without changing the chemical compounds. Not all of the enzymes work the same. Some of the enzymes can either be affected by a different pH, or a different substrate concentration
