15th Influence of pH on Enzyme Activities How does the pH of solution influence the speed of enzyme activities? Enzymes are protein catalysts and chemical that speed up chemical reaction without being involved in the reaction. They are involved in the human digestive system to help people digest food more efficient. Food are substrates to be break down and absorb through the digestive system in the body. Substrate is a molecule that bond with the active site of enzyme to transfer in to one or

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

The Effect of Temperature on the Enzyme Catalase Stephen Francis Biology 183 Abstract This experiment was performed to determine the resultant effect of temperature change on the reaction between the enzyme catalase and hydrogen peroxide. This experiment was performed by measuring and comparing the amount of oxygen bubbles produced and the absorbance of the catalase and hydrogen peroxide solution over time at room temperature‚ 2°C‚ 50°C‚ and 60°C. The overall result of this experiment proved

and Virology. The objective of my thesis was to produce and characterize thermostable β-Galactosidase enzyme‚ which has been explored in various biotechnological‚ industrial‚ medical and analytical applications. The focus of research was not only limited to thermo stability of β-Galactosidase‚ but also to the production of large amount of enzyme in a short period of time. The β-Galactosidase enzyme hydrolyzes lactose into galactooligosaccharides‚ which are suitable for lactose-intolerant people and

Enzymes and their importance in plants and animals (25 marks) Enzymes are biological catalysts‚ which accelerate the speed of chemical reactions in the body without being used up or changed in the process. Animals and plants contain enzymes which help break down fats‚ carbohydrates and proteins into smaller molecules the cells can use to get energy and carry out the processes that allow the plant or animal to survive. Without enzymes‚ most physiological processes would not take place. Hundreds of

Core Practical: Enzyme concentrations and enzyme activity. Introduction In this experiment I shall investigate how the enzyme concentration can affect the initial rate of reaction. I will measure the effect of the enzyme in 5 different concentrations against the controlled variable of the reactant. The enzyme which will be used is different concentrations of potato and the reactant used will be Hydrogen Peroxide. Hydrogen Peroxide which will be the buffer solution is a PH of 7.2. My hypothesis

BIOLOGY HSC NOTES MAINTAINING A BALANCE • Identify the role of enzymes in metabolism‚ describe their chemical composition and use a simple model to describe their specificity on substrates. Enzymes are protein molecules that allow the body to engage in chemical reactions‚ such as metabolism. There activities can be catalytic (being able to control the rate of either increasing/decreasing chemical reaction) Enzymes have a specific shape‚ and this shape must be intact‚ otherwise the effectiveness

Experiment 4 – Effect of Temperature on Enzyme Activity Aim To study the effects of temperature on the activity of amylase enzyme on starch solution. Introduction Enzymes are widely known as biological catalyst. Almost all cellular reactions are controlled and guarded by enzymes. Virtually every metabolic reaction which takes place within a living organisms are catalyzed by enzymes. Enzymes are complex three-dimensional globular proteins. Some of the enzymes are built up off proteins and some

Temperature and enzyme activity Aim: To determine the effect of which the temperature of the enzyme has on the rate of the enzyme catalysed reaction. Hypothesis: The rate of reaction of an enzyme catalysed reaction will increase as the temperature of the enzyme approaches the optimum temperature. Surpassing the optimum temperature will result in a drop in enzyme activity. Materials: 6% hydrogen peroxide Liver suspension 10 test tubes 4 beakers Thermometers Measuring cylinders Test
