Enzymes are protein‚ they are used to catalyse metabolisms in all organisms. They break down complex molecules and build up complex molecules from simple molecules‚ these two processes are catabolic reaction and anabolic reaction respectively. Enzymes are needed in these two processes to catalyse releasing and taking up ATP molecules. Different sequence of amino acid produces different structure of protein‚ which determines the property of protein‚ thus each kind of enzymes has its unique active

Task 1: Introduction In this task I will investigate how the enzyme lactase breaks down the disaccharide lactose into monosaccharides‚ which are glucose and galactose. The main aim will be to get lactose – free milk as milk contains lactose. When we drink milk we need lactase (enzyme) to break down the lactose‚ which is contained by the milk. Once I have created my own method of enzyme immobilisation of lactose using lactase I will then construct a bioreactor. I have looked at and researched

on the rate of enzyme activity of Catalase Aim To investigate the effect of substrate concentration (manipulated by increasing concentration of hydrogen peroxide) on the rate of enzyme activity of catalase‚ produced by liver cells‚ on the decomposition of hydrogen peroxide. Introduction Enzymes are biological catalysts that increase the rates of reactions. In an enzyme-catalyzed reaction‚ the substrate binds to the active site and forms enzyme-substrate complex with the enzyme through the lock

How Enzymes Work In Different Environments By Sarah Smith Biology1111 October 20‚ 2011 Lab Partner: Nellie Greer ABSTRACT Peroxidase is an enzyme found in potatoes that catalyzes the breakdown of hydrogen peroxide‚ H2O2‚ into O2 gas and water. We examined the different pH environments that can affect the enzyme activity during the breakdown of H2O2. In order to do this‚ we added different levels of pH‚ low‚ medium‚ and high‚ into different test tubes with the enzyme and H2O2‚
Premium Enzyme PH Chemical reaction
The effect on rate of an enzyme catalysed reaction by different objectives which include effect of substrate‚ temperature‚ ph and effect of a competitive inhibitor phosphate ions. This is determined by the reaction of hydrolysis by p-nitrophenylphosphate (PNP) as a substrate by the enzyme phosphatase. Abstract The hydrolysis of p-nitrophenyl phosphate has been studied in human red blood cells. To see if hydrolysis was related to the functioning of the sodium pump. Acid phosphatase catalysis’s

An experiment to investigate the effect of temperature on the rate of reaction of the Enzyme Trypsin. Aim: This investigation was on the effect temperature has on the rate that the enzyme trypsin hydrolyses its substrate‚ a protein found in milk (casein). This investigation was conducted under controlled conditions‚ the temperature being the changeable variable. Trypsin and its substrate (powdered milk which is a source of the protein casein) were heated in a water bath. The contents of the two

An Investigation on the rate of reaction of the enzyme Catalase on the substrate Hydrogen peroxide. Plan Aim: To investigate the rate of the effect of Catalase on hydrogen peroxide. Introduction This investigation will be carried out to investigate the rate of reaction of the enzyme catalase on the substrate hydrogen peroxide. Enzymes are biological catalysts‚ which speed up the rate of reaction without being used up during the reaction‚ which take place in living organisms. They do this by

Enzyme Specificity Using Beta-galactosidase and Alpha-galactosidase Introduction: In order to survive‚ organisms need reactions to occur at a certain time and place. Enzymes make these reactions happen. Enzymes are highly specific causing only one enzyme to catalyze one reaction. “Induced fit” explains why enzymes act this certain way. An enzyme will surround a certain substrate and form to it for the reaction to occur in the active site. If it doesn’t form to it‚ the reaction will not occur

VARYING EFFECTS OF ENZYME CONCENTRATION ON REACTION RATES OF MALATE DEHYDROGENASE CELL BIOLOGY 13 NOVEMBER 2007 Enzymes are biological catalysts. They are proteins that speed up reactions with low concentrations. These enzyme proteins are made up of linkages of amino acids. The links coil‚ and coil again forming a tertiary structure. This structure has a groove in it called an active site. The active site is
