Observing Enzyme Activity Purpose: The purpose of this experiment was to test whether the pH affected the enzyme reaction rate. Hypothesis: If the enzyme is in a basic solution‚ then it will react faster because the enzyme (catalase) reacts better in basic solutions. Materials: 10 potato cubes (1 cm3) -Pipet Baking soda solution -50 ml glass beaker Bleach Water Lemon juice Vinegar 5 glass test tubes Drying rack Timer Graduated cylinder Hydrogen peroxide Procedure:

January 2012 How to Plant Rice. Do you know what rice is only when it’s on your plate? Rice is eaten worldwide in all forms and styles‚ but do people really know where this rice came from or all the hard labor put into producing this amazing source of food? When it is covered by a brown hull‚ rice is called paddy; rice fields are also called rice paddies‚ or paddy fields. When planting rice‚ these are some important steps you will need to know in order to have a successful

Sexual reproduction has been successful among flowering plants and mammals‚ it is brought by the following requirements. Firstly is the transfer of gametes. Sexual reproduction is only made successful when the gametes of the male and female from a pair of parents of different sexes are transferred to meet each other. In mammals‚ the male gamete is transferred to the female body by copulation to meet with the female gamete in the oviduct for successful fertilization. However‚ the ovum is only

Lab 2: Animal and Plant Cells Purpose: To examine the differences between single cell and multi cell organisms in terms of Animal and Plant cells. Question: What are the differences between multi and single celled plant and animal organisms? Prediction: Spirogyra Cell: The parts of the spirogyra cell that will be visible under the microscope will be; cell wall‚ cell membrane‚ nucleus‚ chloroplasts‚ vacuole and cytoplasm. Banana Cell: The parts of the banana cell that will be visible

The effect of time on enzyme reaction. Abstract: In this lab investigation we will observe how the amount of hydrogen peroxide is affected by catalase over time. The enzyme was added to 10 mL’s of hydrogen peroxide and observed over time to determine the relation between time and enzyme activity. The hypothesis stated that as time increased substrate would decrease. Therefore I predicted that at 60 seconds‚ there would be the least amount of H2O2. The enzyme activity mirrored my predictions

Varibles that affect Enzyme Catalysis Reaction Rates Introduction Molecules are constantly moving in our bodies and in nature. When molecules move fast enough they collide into one another‚ allowing chemical reactions to occur. Factors such as temperature and concentrations can either help increase or decrease these reactions. (Jubenville.) Enzymes are known as catalyst because they are able to speed up reaction rates without being destroyed or altered. They are able to encourage chemical reactions

Use of Enzymes in Food Industry - Food industry utilizes a variety of enzymes for processing of various foods‚ e.g.‚ production of various types of syrups from starch or sucrose (a- and β- amylases‚ glucamylase‚ pullulanase‚ invertase‚ and glucose isomerase)‚ meat/protein processing using proteases‚ removal of glucose and or molecular oxygen (O2) using glucose oxidase and catalase‚ use of lactase in dairy industry and use of enzymes in fruit juice and brewing industries. Glucose oxides are obtained
