effect of pH on enzyme activity Rationale Amylase is an enzyme involved in the digestion system which catalyses the breakdown of starch into sugars. It is not only present in human saliva but also in the pancreas‚ where it hydrolyses dietary starch into disaccharides and trisaccharides which are converted by other enzymes to glucose to supply the body with energy. pH has an effect on the activity of all enzymes‚ including amylase. As the pH level increases‚ the enzyme activity increases‚ up until

CHAPTER ONE 1.0 INTRODUCTION 1.1Background information A joint study by United States Agency for International Development (USAID) and United Nations International Children Education Fund (UNICEF) and Joint United Nations Program on HIV/AIDS (UNAIDS) found out that at the end of 2001‚ 13.4million children under the age of 15 had lost one or both parents to Acquired Immune Deficiency Syndrome (AIDS). The increase in AIDS‚ which orphans many children‚ is one of the major challenges in many countries

Discuss factors affecting the accuracy of eyewitness testimony. There are factors that affect the accuracy of eyewitness testimony such as emotions‚ fundamental attribution bias‚ face recognition in other races‚ leading questions and many more. An example of the affect factors such as leading questions can have on eyewitness testimonies is the Loftus and Palmed study (1974). It’s has been proposed that we store a series of incomplete memory fragments in our mind. When we need to recall a

College grading is an exceptionally complex phenomenon because it is subject to both external social forces and internal changes of the participants (for example‚ students‚ faculty) policies and practices (for example‚ grading policies) and other factors (Birnbaum‚ 1977)Ecoamists view grades as a reward for academic performance‚ which is assumed to be related to individual academic ability as well as the quantity and effort the student puts forth in educational activites (Becker‚ 1965; Hanushek 1979)Psychologist

State the factors affecting the price elasticity of demand? The type of product will affect the price elasticity of demand i.e. a necessity such as petrol will have a inelastic demand as it is a must have for consumers so a change in price will cause only a minor change in price whereas if a product is not a necessity for consumers it will have an elastic demand meaning a small change in price could lead to a greater change in quantity demanded The proportion of the consumers income spent on a product

20th‚ 2012 Enzyme Lab What is an enzyme? Enzymes are specialized protein molecules simplifying most of the body’s metabolic processes such as‚ supplying energy‚ digesting foods‚ purifying your blood‚ executing the body of waste products etc. Enzymes act as catalyst by speeding up the reactions that happen in our bodies and decreasing the amount of activation energy needed to break a complex down. A reactant is any given enzymatic reaction is called a substrate for that specific enzyme. The place

Enzymes are biological catalysts‚ large protein proteins that have a very specific three-dimensional shape which makes them highly specific and only work on one or a few similar chemical reactions. Enzymes themselves are not consumed in the reaction‚ but they help attract substrates into correct position to undergo chemical reaction. Enzymes greatly speed up the rate of biological reactions by lowering the energy of activation. To get a sense of the speed and efficiency of enzymes‚ substrates can

Chapter I THE PROBLEM AND ITS BACKGROUND Introduction Education is everyone’s concern. In 1990‚ the United Nation Education‚ Scientific and Cultural Organization (UNESCO) launched Education For All (EFA)‚ the movement to provide quality education for all children‚ youth‚ and adults globally by the year 2015. The right to education is universal and extends to all children‚ youth and adults with disabilities. This right is enshrined in the Convention on the Rights of the Child (1989) and the
