of the increase in the enzyme concentration on the rate of reaction. By using self investigative and experimental skills‚ the experiment was done in order to determine how the rate of reaction will be altered‚ whether it will increase‚ decrease or remain constant when the different concentration of enzymes added. INTRODUCTION: Enzymes are produced naturally in plant‚ animal‚ and microbial cell. There are thousands of different enzyme can be found in any cell. Enzymes can be describe as molecules

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

Inhibitory and Non-Inhibitory Competition‚ Enzyme-Substrate Concentration‚ Along with Varying Temperature and pH-Balanced Environments on the Enzyme-Catalyzed Reaction of pNPP Abstract: Introduction: Many of the chemical reactions‚ which take place in in living things are controlled by enzymes. In such cases‚ the enzyme is a protein in the cell which lowers the activation energy of a catalyzed reaction‚ which serves to increase the rate of the reaction. Alkaline phosphatase is made throughout

the effect of temperature on an enzyme controlled reaction Introduction and planning For the investigation of enzymes‚ I am going to conduct an experiment to see how temperature can affect the rate of reaction of enzymes by testing it with starch. The enzyme that we are going to use is called amylase. We are going to test this enzyme with starch. By mixing amylase and starch solutions together under different temperature conditions‚ we can record the rate of reaction by taking a sample out and test

The Energetic Salesman 1. Backgrounds factors Keith Swanson graduated from a prestigious university that was considered as one of the best business school in the country. He was really good student‚ his school average of the marks was B+. He was focused on studying the marketing and finance. Although he had good results in the school‚ he was active in many other fields. For example Keith was the member of the university golf team‚ he was active in intramural sports and he was a vice-president

Aim: This experiment will aim to show how the amount of substrate affects the rate of the reaction. Hypothesis: In this experiment I think the amount of substrate will simply increase the reaction. As I increase the surface area of the potato the gas given off from the reaction will increase. Therefore to sum things up‚ my hypothesis is when the Independent variable increases so will the dependant variable. Independent variable: - Surface area of potato Dependant variable: - Gas Controlled

Lab Report Factors That Affect Enzymes Reaction Rate Name of lab: Effects of temperature‚ pH‚ Enzyme Concentration‚ and Substrate Concentration on Enzymatic Activity Introduction: Enzymes are the most important types of proteins‚ they act as catalysis (speed up chemical reactions). If enzymes didn’t exist‚ biochemical reactions would act to slowly and they couldn’t keep up with the metabolic functions. Enzymes have a three-dimensional structure that is really complex. This structure consists

Enzymes (pron.: /ˈɛnzaɪmz/) are large biological molecules responsible for the thousands of chemical interconversions that sustain life.[1][2] They are highly selective catalysts‚ greatly accelerating both the rate and specificity of metabolic reactions‚ from the digestion of food to the synthesis of DNA. Most enzymes are proteins‚ although some catalytic RNA molecules have been identified. Enzymes adopt a specific three-dimensional structure‚ and may employ organic (e.g. biotin) and inorganic (e

Determination of the activation energy of an enzyme catalysed reaction Introduction In this practical the aim for this experiment was to find out the catalytic power of alkaline phosphate‚ as well as the rate of reaction and the activation energy of p-nitrophenol phosphate. Enzymes are biological molecules that catalyse a chemical reaction. ‘Enzymes work by lowering the activation energy of a chemical reaction making it easier to proceed’ [1]. This allows molecules to have more energy therefore
