Enzyme Inhibition Many drugs exert their action by inhibition of an enzyme activity in the body. If the activity of an enzyme is vital to the cell or organism‚ then inhibition may lead to death of the cell or organism. It is now possible to design new drugs which are enzyme inhibitors once a target enzyme has been identified. Types of Inhibitors A) Reversible Inhibitors: The effect of the inhibitor is instantaneous‚ and it can be removed from the enzyme by dialysis so that the enzyme activity

construction material and magnetic materials fields. Temperature of ball mill has an important impact on the quality of products. To understand the issue of temperature control of ball mill can better finish grinding. Temperature of ball mill is big issue. Appropriate temperature must be set in production. Temperature not only affects the properties of ball mill material but also the grinding performance of grinding materials. The normal temperature of ball mill is high and there are many reasons

affecting Rates of a Reaction (Kinetics) KINETICS DESIGN LAB Research Question: Does the concentration of Potassium Iodide (KI) affect the rate of its reaction with hydrogen peroxide (H2O2) (of a fixed concentration)? Introduction: There are several factors that affect the rate of a reaction. Some of them being Pressure (if the reactants are Gases)‚ Temperature‚ Presence of a Catalyst‚ Surface Area of the reactant‚ and Concentration. According to the Collision Theory‚ during a reaction‚ particles

ENZYMES LABORATORY REPORT Introduction The utilization of any complex molecule for energy by an organism is dependent on a process called hydrolysis. Hydrolysis breaks complex molecules into simpler molecules using water. Similarly‚ the process that is the reverse of this is called dehydration synthesis‚ which removes water from simpler molecules. However‚ because hydrolysis occurs very slowly‚ living organisms use biochemical’s called enzymes to speed up the reaction. In this lab exercise

Period 2 January 26‚ 2013 Enzyme Catalysis Lab Report Background: Enzymes are catalyst‚ which affect the rate of a chemical reaction. One consequence includes the cell to carry out complex chemical activities at relatively low temperatures. In these reactions the substrate binds reversibly to the active site. The cause of this is a decrease in the energy needed to activate the reaction of the substrate molecule to from products. Every enzyme is particular for a reaction for the reason of its amino

bleaches. Now bleach - in scientific terms - is a kind of catalyst. A catalyst is a chemical that increases the reaction rate of a chemical reaction (catalyse)‚ and the chemical reaction involves enzymes. So to understand how bleach works‚ we first understand how enzymes work. Enzymes Enzymes are the most important thing in our lives‚ it makes the world go ‘round! Enzymes are proteins that acts as catalysts and help combine or break down hydrogen peroxide. Imagine a pen with ink inside

Introduction We are going to do an experiment to see how surface area effects the rate of reaction when added to hydrochloric acid. I will add calcium carbonate (marble chips) to hydrochloric acid. When calcium carbonate is added to hydrochloric acid a reaction takes place. The solution fizzes and gives off the gas carbon dioxide. I will collect this gas in a gas syringe and will time how long it takes for the reaction to produce 100cm3 of carbon dioxide. CaCO3 +2HCL Co2 +CaCl2 +H2O CalciumHydrochloricCarbonCalciumWater

Investigating the effects of changing temperature on the activity of enzymes Background information: Renin is an enzyme that catalyses the coagulation of milk. It is found in the stomach of many animals and is used in making cheeses and junkets. It is found in the gastric juices or gastric mucosa of many mammals‚ including humans. In the human stomach‚ particularly those of infants‚ rennin works to curdle milk so that pepsin‚ another stomach enzyme‚ can further breakdown the proteins into absorbable

Chemical reactions can happen slowly or fast. The speed of the reaction rate can be changed. Some of the factors that can affect the reaction rate are surface area‚ temperature‚ and concentration and pressure. Surface area is the exposed‚ outer layer of a solid. Increased surface area increases reaction rate because more particles on the surface of a solid come in contact with the particles of another substance. For example‚ if you place a donut stick into water‚ the donut will react slowly with
