purpose of this evaluation is to make provisions for guiding the growth of the learners to diagnose their strengths and weakness and point out areas where remedial measure are devised. It makes a judgment on the quality or worth of an educational program or students’ achievements and provides for a subsequent modification of curriculum. Also‚ teachers have a key role to play in the curriculum renewal and development process. According to the types of information they provide to decide a test is suitable

Enzyme Catalysis Introduction: Enzymes are produced by living organisms as proteins. These enzymes perform as catalysts to bring about a chemical reaction. In fact‚ most reactions are catalyzed by enzymes during reactions in the cell or in the human body. A catalyst that enzymes pose ad are by definition substances that are capable of initiating or speeding up a chemical reaction. Catalyst are not a necessity during a chemical reaction‚ they are just used to speed up a chemical reaction. This event

Lab: Catalase (Enzymes) Abstract In this laboratory exercise‚ studies of enzyme catalase‚ which accelerates the breakdown of hydrogen peroxide into water and oxygen. The purpose was to isolate catalase from starch and measure the rate of activity under different conditions. The laboratory was also conducted in association with a second laboratory that measured the effects of an inhibitor on the enzymes. Changes in temperature and pH along with Substrate Concentration and Enzyme Concentration

Across the globe‚ animals of all varieties are being exploited for their flesh‚ fur and produce. How would you feel if your pets were subjected to such cruelty? Animals are poisoned‚ stabbed and crammed in cages to be tested on; medical research‚ educational purposes‚ drug and chemicals‚ and cosmetics and household products are some of the main reasons why they are put through such torture. Even though there may be some ‘valid’ reasons for conducting and carrying out such inhumane activities‚ too

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

Enzyme activity The introduction is a statement of the subject and objectives of the experiment and presents your hypothesis. Relevant background information (appropriately referenced) is given in sufficient detail that a person unfamiliar with the topic can understand the nature of the experiment. A good introduction is clear and concise. Carbohydrates and proteins should be explained in terms of their structure and major functions in cells. Your intro should end with a brief overview of the amylase

"In all history‚ no nation of mere agriculturists ever made successful war against a nation of mechanics You are bound to fail." Union officer William Tecumseh Sherman to a Southern friend. "Why did the North win the Civil War?" is only half of a question by itself‚ for the other half is "Why did the South lose the Civil War?" To this day historians have tried to put their finger on the exact reason for the South losing the war. Some historians blame the head of the confederacy Jefferson

The Rate of Reaction that Enzyme Concentration‚ pH‚ and Temperatures Have on the Amylase Enzymes Color Disappearance Abstract: Compare reaction rates of the concentrations‚ pH’s‚ and temperatures of the enzyme Amylase. At what concentrates do the substrate molecules collide with each other‚ making the reaction possible? At what pH levels do the 3D molecular structures change breaking the H-bond and/or denaturize? At what temperatures do the collisions of the substrate molecules happen

Notes The Forgotten War President Truman‚ politicians‚ and most Americans believed the Korean police action would be over in a matter of weeks. It could be as simple as the United Nations (UN) passing a resolution to have North Korea return to its territory. No one‚ including the UN‚ Soviet Union‚ Communist China‚ or the United States and its allies‚ wanted an all-out war. However‚ the conflict in Korea became much more than just a police action. Thousands of military personnel and civilians

Temperature on Enzyme Activity and Oxygen Production Throughout this report you will gain information as to how temperature effects the amount of oxygen produced in an enzyme- catalase experiment. In the experiment we used liver extract as a catalase and created a chemical reaction within a reaction chamber between the catalase and hydrogen peroxide as well as three different controlled temperatures. In the procedure below there will be a step by step process as to how the experiment
