The Effects of pH‚ Temperature‚ Enzyme‚ and Substrate Concentrations on Benzoquinone Production BIOL 2051 June 10th 2013 Introduction Enzymes are the ultimate catalysts of living things. Enzymes are made of proteins which are structured and directed by amino acids chains. Enzymes attract and fit substrate molecules to an active site. The active site binds the substrate molecules covalently to enzyme forming an enzyme-substrate complex‚ which catalyzes

Jennifer Anatomy and Physiology Enzyme Lab Report Introduction The chemical reaction that is being studied is the hydrolysis of starch. The enzyme that is being studied is amylase. This experiment is looking at the effect of temperature on the rate of the enzymatic hydrolysis of starch. My hypothesis is that the higher the temperature the faster the hydrolysis of the starch would occur. The rationale behind this is that heat

Catalase Enzyme Lab Samiya Hussein March 9‚ 2012 Introduction In order to receive the necessary amounts of energy required for daily function‚ the digestive system must break down proteins‚ fats and carbohydrates. In doing so‚ the body produces poisonous chemicals; however‚ the cells aren’t harmed. This is because enzymes are used to break down these chemicals. The name of the enzyme that was the main focus of the lab is catalase. Catalase is responsible for catalyzing hydrogen peroxide

Introduction Enzymes are protein based structures that help speed up chemical reactions. They help these reactions keep up with the everyday metabolic needs and other like functions of organisms. Enzymes are also considered catalysts‚ due to the lowering in activation energy‚ in which they are not consumed or changed at any point during the reaction. These enzymes have three main protein structures that help keep them formed and intact. Stage 1 of these structures is the primary structure‚ which

Ye Tao BISC220-13155 The Effect of Temperature on the Digestion of Starch by Activity of Enzyme α-Amylase: Observation of Rate of Starch Disappearance through Iodine Test Introduction An enzyme is a type of protein that‚ through its own structure including hydrogen bonds‚ acts like a biological catalyst and is able to accelerate the biochemical reaction rate by lowering the activation energy of the whole process‚ without which cells could hardly practice any physiological functions within human

Meerra Gandi‚ Erin Barody‚ Samantha Gutcho Title: The Effect of Adjusted Concentration of Hydrogen Peroxide on the change in reaction rate of liver catalase. Hypothesis: Null Hypothesis: If the concentration of the Hydrogen Peroxide is changed then there would be no change in the reaction rate. Alternate Hypothesis 1: I there is an increase in concentration in concentration of Hydrogen Peroxide then the reaction rate of the liver catalase will increase. Alternate Hypothesis 2: If there is an increase

Enzyme Report Case 1 - Hereditary Fructose Intolerance 1 & 2. Enzymes take on a variety of roles in the human body at the cellular level. Specifically‚ they aid in the breakdown of macronutrients such as glucose and fructose so that the body can use them. Although reactions within the body would occur without enzymes‚ enzymes provide control because the reaction is not needed all of the time. Enzymes function in specific environments such as temperature or pH; some enzymes are specific

The purpose of this review paper is to discuss the effect of temperature on enzyme- catalyzed reactions. This is relevant because many diseases can be diagnosed and controlled by the processes of enzyme activity (Worthington 2015). If more information is not found about enzyme activity and how it is affected‚ many diseases may go undiagnosed and uncontrolled. Temperature is a type measurement that does not only consist of heat. It is the measurement of the mean kinetic energy of any group of particles
Premium Enzyme Chemical reaction Catalysis
Structure: Enzymes are globular proteins that act as catalysts‚ they have a specific 3D shape that is the result of their amino acid sequence. There is a specific region of the enzyme that is functional‚ this is called the active site. The active site is made up of a small number of amino acids and forms a small depression within the larger enzyme molecule. Moreover‚ the molecule that the enzyme acts upon (substrate) fits precisely into the depression and forms an enzyme-substrate complex. The substrate

in these reactions‚ resource‚ products and enzyme are three most mainly things. In all chemical reactions‚ there is a activation energy(EA) needed for them. However‚ if the rate of reactions are too low‚ they will not be able to sustain lives. In this case‚ they have enzyme as a protein catalyst. As reaction catalysts‚ enzymes are proteins that adjust the process by initiating the reaction. In this case‚ there are also many elements that influence enzyme working rates. For example‚ most living things
