Meghann Kiphart AP Biology Lab Report Number One Mrs. Irvine Introduction: Because all molecules have kinetic energy and are constantly in motion cells go through a process called diffusion. Diffusion is the movement if molecules from an area of higher concentration to and area of lower concentration. This process with continue to occur until an equilibrium is reached. Osmosis is a different and unique kind of diffusion. Osmosis is the diffusion of

Enzyme Kinetics Examples and Problems 1. An enzyme is produced for producing a sun protection lotion. Given kinetic data for the enzyme reaction with Vm=2.5 mmol/m3.s‚ Km=8.9 mM and So=12mM‚ what would be the time required for 95% conversion in a batch reactor? 2. An enzyme was assayed at an initial substrate concentration of 10-5M. The Km’ for the substrate is 2x10-3M. At the end of 1 min‚ 2% of the substrate had been converted to product. a. What % of the substrate will be converted

Title: Kinetics: The Rate of a Chemical Reaction Objectives: 1. To study the kinetics of chemical reaction‚ 2 I- + S2 O82- I2 + 2 SO42- . 2. To study the effects of reactant concentration (persulphate‚ S2O82-‚ and iodide‚ I-) and temperature on the rate of chemical reactions. ( i) Study the effect of 0.20M (S2O82-) on the rate of chemical reaction. ( ii) Study the effect of 0.10M (S2O82-) on the rate of chemical reaction. ( iii) Study the effect

Chemistry Module Six: Thermochemistry and rate Study sheet for the test G.01: Thermo-chemistry I. Temperature and Thermal Energy Temperature is a measure of the average kinetic energy of the particles in a sample of matter. The greater the avg. kinetic energy of the particles in a sample of matter‚ the higher the temperature of that matter. Some temperature scales are Fahrenheit‚ Celsius and Kelvin. Thermal energy is the measure of the total kinetic energy in a sample. And Temperature

The Chemistry of Lipids Experiment #8 Objective To observe the solubility of lipids in polar and nonpolar solvents and to compare saturated and unsaturated fats in their chemical reaction with bromine. The percent fat in a food will be determined by extraction of the fat and weighing it. Introduction Lipids‚ by definition‚ are natural substances that do not mix with water but dissolve in organic solvents. There are several classes of lipids‚ including: fatty acids‚ waxes‚ triacylglycerols

Standardize a solution of potassium manganate(VII) by an iron (II) salt (ammonium iron (II) sulphate) Introduction Oxidation numbers describe the number of electrons the atom will gain or lose during a reaction. Each atom in an equation can be assigned an oxidation number according to certain rules. If the oxidation number of an atom increases as you go from the left side to the right side if an equation‚ oxidation has occurred (electrons have been lost); if the oxidation number decreases
