Lab 4 Quiz 1. Enzymes and what is their function? a. Enzyme: biological catalysts that regulate chemical reactions that occur in cells. Responsible for things such as converting food to energy‚ replace old damaged tissues‚ disposal of cellular waste products. Are responsible for lowering the activation energy. 2. Most enzymes are proteins with three-dimensional shapes determined by their amino acid sequence. 3. Substrate – is a reactant molecule that binds to the highly specific active site

Introduction: Enzymes are a substance produced by a living organism that acts as a catalyst to activate a specific reaction. The purpose of this experiment was to figure out if the temperature of the reaction would rise‚ will the absorption rise as well. Reactions use energy‚ If there is energy than heat occurs. The Hypothesis that was figured out was‚ If the temperature rises‚ then the absorption will also go up. The Independent variable that was tested was temperature. The dependent variable that

Enzyme are a very important component in living organisms. If enzymes did not exist than life itself would not exist (Lab Manual 3 pg. 1). They help in many different ways that are useful to the body of living organisms. Enzyme are used to speed up chemical reactions (Lab Manual 3 pg. 1). Through this process‚ they are considered very unique because they are not altered or consumed within the reaction (Lab Manual 3 pg. 1). This is why enzymes are considered biological catalysts. They also do not

Name : Andi Nadya Amanda Period : 4 Grade : 11 Enzyme Lab Report Question How heats effect the length of reaction time of an enzyme? Hypothesis I think the heat will make the length of reaction time of an enzyme become slowly. Heat is one of a way to denature the substrate. It means the heat will break down the structure of substrate in order the reaction of enzymes that we activated into it become slowly. Method for Collecting Data First I will record the length of reaction time

Enzymes are catalytic proteins that speed up chemical reactions by lowering the activation energy of the reaction. our body cells depend highly on enzymes to complete many important functions‚ such as digestion and metabolism. Enzymes are selective‚ in which each enzyme can only speed up a specific reaction. There are molecules that enzymes work with called substrates. substrate bind to an area of an enzyme called active site. There is specificity between the enzyme and substrate that react with

structures of cells but they act as enzymes in reactions of the body1. Enzymes are biological catalysts that lower the amount of activation energy needed in carrying out biochemical reactions1. Enzymes are responsible for almost every reaction that occurs in a cell and is named according to the substrate they specifically affect. An enzyme works best under optimal conditions pertaining to temperature‚ pH level and salt concentration1. In unfavorable conditions enzymes will become denatured and ineffective

Catalase Enzyme Lab Samiya Hussein March 9‚ 2012 Introduction In order to receive the necessary amounts of energy required for daily function‚ the digestive system must break down proteins‚ fats and carbohydrates. In doing so‚ the body produces poisonous chemicals; however‚ the cells aren’t harmed. This is because enzymes are used to break down these chemicals. The name of the enzyme that was the main focus of the lab is catalase. Catalase is responsible for catalyzing hydrogen peroxide

5C(21) Effects of temperature on the activity of lipase Aim: To investigate the effects of temperature on the activity of lipase enzyme on milk which contain fats or lipids. Introduction: Enzyme is a kind of biological catalyst that made up of protein. It can speed up the metabolic reactions on various kinds of substances. Like lipase can break down lipid into glycerol or fatty acids in milk. Since enzyme is made up of protein which easily affected by varies temperature. This experiment is carried

Experiment 1: Error‚ Uncertainties and Measurements Laboratory Report Jan Luke Mendoza‚ Alexis Vienne Munar‚ Paula Murakami‚ Giorla Joanne Negre Department of Math and Physics College of Science‚ University of Santo Tomas Espana‚ Manila Abstract Throughout the experiment the main goal is to find out about the realities in taking measurements‚ that is‚ that there will always be an uncertainty for each acquired value. And to find out and recognize these uncertainties was handled in the

Enzymes are proteins or nucleic acids that catalyze reactions. They are able to speed up reactions by reducing the activation energy of a reaction. Each kind of enzyme has a specific shape that matches its substrate so it can bind to its active site. Enzymes convert their substrates into a product. Enzyme activity are affected by factors such as temperature‚ pH‚ and time. If an enzyme is exposed to extreme heat‚ it will become denatured‚ that is‚ to become deformed and lose its original shape which
