Name ____________________________ Date ____________ THE EFFECT OF CONCENTRATION ON THE RATE OF DIFFUSION PURPOSE: This experiment will explore the concentration gradient by measuring the rate of diffusion in a number of theoretical cells. The objectives for this lab are: (1) To define concentration gradient‚ (2) To explain experimental data concerning different concentration gradients‚ (3) To complete a data table and prepare a graph to illustrate the data‚ and (4) To apply information from

Lab Report An enzyme is a protein that speeds up the rates of chemical reactions. They recognize‚ bind‚ and change specific reactants. They do not change so they can catalyze the same reaction again and again. Activation energy is the amount of energy needed in order to begin a chemical reaction. A Catalyst is a substance that increases the rate of a chemical reaction without itself undergoing any permanent chemical change. Catalysts are substances or a substance that configures another substance

Abstract: The Enzyme Lab results where when the liver was frozen‚ its reaction was fast‚ and when it was hot‚ it was slow‚ and the liver that was at room temperature reacted slowly to medium. Introduction: The Enzyme Lab is to conduct investigations to determine the most favorable conditions for the most efficient enzyme activity. Variables to be used testing include temperature‚ pH values and surface area. Enzymes are proteins that speed up the rate of chemical reactions‚ which would otherwise

Procedure: The first part of this lab involved the standardization of the base NaOH with potassium hydrogen phthalate‚ or KHP. First‚ about 400 mL of NaOH (10 M) were poured into the 600-mL beaker. This was used to fill the burette. The 50-mL burette was rinsed through twice with 5 mL of NaOH. Then‚ the burette was mounted on the ring stand using a burette clamp and filled to 0 mL. Some of the NaOH was drained to fill the tip of the burette. The initial volume of NaOH‚ rounded to two decimal places
