Lab Report Factors That Affect Enzymes Reaction Rate Name of lab: Effects of temperature, pH, Enzyme Concentration, and Substrate Concentration on Enzymatic Activity Introduction: Enzymes are the most important types of proteins, they act as catalysis (speed up chemical reactions). If enzymes didn’t exist, biochemical reactions would act to slowly and they couldn’t keep up with the metabolic functions. Enzymes have a three-dimensional structure that is really complex. This structure consists
Enzymes and Factors That Affect Them Rewrite title Zuryab Rana October 21, 2017 Abstract: In the experiment we used Turnip, Hydrogen Peroxide, Distilled Water, and Guaiacol as my substances. On the first activity, Effect of Enzyme concentration of Reaction Rate for low enzyme concentration, we tested three concentrations of the turnip extract, and hydrogen peroxide. For the Turnip Extract I used 0.5 ml, 1.0 ml, and 2.0 ml. For hydrogen peroxide we used 0.1 ml, 0.2 ml, and 0.4 ml. We used a
Enzymes: Helpful or Harmful? Abstract Enzymes act as catalysts to normalize the speed of the many chemical reactions involved in the Metabolism, of living organisms (2016). Because the enzyme-substrate results from weak bonds that require precise positioning of specific amino acid side chains in the active site, any external factors that affect formation of these bonds can significantly affect enzyme function. These factors include pH, ionic strength, temperature, and the chemical environment. Throughout
biological catalyst. An enzyme is a protein that acts as a biological catalyst of chemical reactions and is capable of speeding chemical reactions. The shape of each enzyme is very precise and this gives the enzyme the ability to catalyze one specific reaction. Enzymes have a three dimensional shape, which is essential to the way it functions. In every enzyme there is a region called active site where a complementary substrate molecule binds with it. After this, and the enzyme is ready to bind with
Investigating the effect of pH on the activity of the enzyme catalase. Introduction Hydrogen peroxide (H2O2) is a very pale blue liquid which appears colourless in a dilute solution, slightly more viscous than water. It is a weak acid. It has strong oxidizing properties and is therefore a powerful bleaching agent that is mostly used for bleaching paper. Catalase is a common enzyme found in all living organisms. Its functions include the conversion of Hydrogen Peroxide, a powerful and potentially
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
Laboratory 7: Environmental Effects on Enzyme Activity BI-185-03 BY Charlie Kane 10/24/17 Abstract During this experiment we tested the effects that specific environmental conditions have on the enzyme, peroxidase. Through this experiment we developed an understanding of enzymes and their functions. By exposing the enzymes to different environments, we observed a changed in their activity. In order for us to measure these changes we used the technique of spectrophotometry, meaning we used
1: How does the concentration of substrate affect the reaction rate? Hypothesis: If the concentration of a substrate increases, any time an enzyme happens upon a substrate it will be free to help that substrate react, but then when an enzyme encounters a new substrate at a slightly higher concentration it will already be working on another substrate, therefore, as we increase substrate concentration it is not going to increase as fast as the reaction rate. Argument: Substrates are reacting molecules
of the increase in the enzyme concentration on the rate of reaction. By using self investigative and experimental skills, the experiment was done in order to determine how the rate of reaction will be altered, whether it will increase, decrease or remain constant when the different concentration of enzymes added. INTRODUCTION: Enzymes are produced naturally in plant, animal, and microbial cell. There are thousands of different enzyme can be found in any cell. Enzymes can be describe as molecules
of pH on the Function of the Enzyme Amylase The objective of the lab was to examine the effects of environmental variables on the functions of an enzyme. To the point, an experiment was conducted to test the effect of pH on the function of the enzyme Amylase. Enzymes are proteins that act as catalysts and help reactions take place. In short, enzymes reduce the energy needed for a reaction to take place, permitting a reaction to take place more easily. Some enzymes are shape specific and reduce
