Enzymes are catalytic proteins which speed up the rate of reactions. Every enzyme has a specific function – meaning‚ they can only bind to certain substrates. Because these enzymes are proteins‚ they can be denatured. Enzymes can be denatured by many factors‚ such as pH and temperature. This lab was divided into three parts which examined the effects of pH‚ enzyme concentration and temperature on the rate of which enzymes catalyze. The pH is an index of hydrogen ions. In acidic conditions‚ where

hydrogen peroxide and potatoes (enzymes)? Introduction The enzyme used for this experiment is Catalase. Catalase is inside mostly any living organism which uses oxygen. Its job is to break down hydrogen peroxide‚ into oxygen and water. (Formula) 2H2O2 ---> 2H2O + O2 (lab manual). There are limiting factors which if altered‚ can alter the procedure of the reaction‚ such as temperature‚ pH‚ and the concentration of either the enzyme or the substrates. Enzymes are specialized class of protein

Technological Advances in the Last Century Nancy September 30th‚ 2012 HUM/186 Mass Media Influences on America In the last century‚ technology has changed mass media immensely. A hundred years ago‚ people would use the post office‚ a rare telephone or word of mouth to communicate across large distances. These were not the most efficient methods of communication. However since then we have developed ways of communicating in faster‚ more effective ways. In the 1920s‚ radios started becoming

With the new technological advances‚ crime has not really decreased much‚ but in fact‚ it has changed in ways of how crime is being committed. Criminals are finding new ways to commit their crimes by using the newer technology advances available not only to investigators‚ but also to the public. Some of these advances include the development of the internet and new features that you might find on a home phone or even a cell phone. Even though these new advances may give criminals the chance to

Enzyme Controlled Reactions 1) Describe the relationship between substrate concentration and the initial reaction rate of an enzyme-catalyzed reaction. Is this a linear relationship? What happens to the initial reaction rate as substrate concentration increases? A) The relationship between the substrate concentration and the initial reaction of an enzyme-catalyzed reaction is very productive‚ but is dramatically affected by the pH level of the given solution. The most productive pH level is

8/12/2013 Intro I am going to investigate a factor that affects the rate of enzyme activity What are enzymes and how do they work? Enzymes are biological catalysts - catalysts are substances that increase the rate of chemical reactions without being used up. Enzymes are also proteins and thus have a specific shape. They are therefore specific in the reactions that they catalyse - one enzyme will react with molecules of one substrate. The site of the reaction occurs in an area on

Title: Enzyme Activity Lab Purpose: To measure the rate of enzyme activity from a tissue abstract and experiment with different factors‚ such as the enzyme solution and the substrate with different hydrogen peroxide percentages and temperature‚ that affect enzyme activity. Hypothesis: 1) If the disk is placed into each beaker with 100 units/ml of enzyme solution‚ then the time for the disk to float will be 30 seconds. 2) If the temperature of the solution is at 5 degrees Celsius‚

LAB 1: What temperature does the enzyme actually work properly in? (Hypothesis) If the temperature is below 40 but above 20‚ then the liver will show bubbles. If the temperature is raised higher than the optimum temperature‚ then an extreme decline in enzyme activity would occur following by the quick denaturing of the enzyme‚ rendering it is permanently useless. Also about 37°C is body temperature. The liver that was at 25°C had a huge amount of bubbles (a 4 on the scale) and the 0°C

telemedicine. Like the terms "medicine" and "health care"‚ telemedicine often refers only to the provision of clinical services while the term telehealth can refer to clinical and non-clinical services involving medical education‚ administration‚ and research.[3] The term eHealth is often used‚ particularly in the U.K. and Europe‚ as an umbrella term that includes telehealth‚ electronic medical records‚ and other components of health information technology.
