temperature on the enzyme activity was that the reaction’s rate would increase as the temperature increased‚ until they go over the optimum temperature where the enzymes denature and the reaction’s rate quickly drops to zero. At 5 degree C the rate is 0.00059mole PNP/min. This then increases to 0.01031mmoles PNP/min at a temperature of 50 degree C. The rate then drops drastically to -0.00215moles PNP/min. This point is where the enzymes have been denatured and have no activity‚ shown as the last point

LAB: Substrate Concentration Affecting the Rate of Enzyme Activity: Through the Experiment of Beef Liver Puree and Hydrogen Peroxide Research Question Does different amount of substrate affect the rate of enzyme activities? Purpose To examine how different types of concentration (Hydrogen Peroxide) affect the rate of enzyme activity. Hypothesis We believe that if there is more substrate concentrated‚ then there will be an increase in the rate of enzyme activity. This is because

and objectives of this lab was to be able to draw completed electrical circuits using the correct symbols for selected electrical components‚ including batteries and diodes. Another focus was to calculate the proper resistance using Ohm’s law‚ use proper electrical currents and quantities‚ and lastly measure voltage and resistance in an electrical circuit using a multimeter. Materials: Wire Light Emitting Diodes (red‚ green‚ blue) Alligator Chips Resistors Multimeter 9-volt battery Procedures:

Activity 9.1 A Quick Review of Energy Transformations Review Chapter 8 and pages 160–162 of Chapter 9 in Biology‚ 7th edition. Then complete the discussion by supplying or choosing the appropriate terms. To maintain life‚ organisms must be able to convert energy from one form to another. For example‚ in the process of photosynthesis‚ algae‚ plants‚ and photosynthetic prokaryotes use the energy from sunlight to convert carbon dioxide and water to glucose and oxygen (a waste product).

Title: Enzyme Activity Lab Purpose: To measure the rate of enzyme activity from a tissue abstract and experiment with different factors‚ such as the enzyme solution and the substrate with different hydrogen peroxide percentages and temperature‚ that affect enzyme activity. Hypothesis: 1) If the disk is placed into each beaker with 100 units/ml of enzyme solution‚ then the time for the disk to float will be 30 seconds. 2) If the temperature of the solution is at 5 degrees Celsius‚

Activity 1: Simple diffusion Introduction: Simple diffusion is the net movement of substances from a region of high concentration to a region of low concentration so its overall net movement is along the concentration gradient‚ simple diffusion does not require energy therefore it is ’passive’‚ substances are diffused across the membrane between the phospholipids. Materials and methods: * 20 mwco dialysis membrane * 50 mwco dialysis membrane * 100 mwco dialysis membrane * 200 mwco
