Abstract: The main objective of this Lab‚ is to experiment with stoichiometric measurements‚ since it is one of the most important subjects in chemistry. In addition‚ stoichiometric measurement is widely used in chemistry‚ because it indicates the proportion of mass in which various substances react. By examining one specific example of stoichiometric determination‚ which is: “Stoichiometry and limiting reacting”‚ we found out the different mass proportions in which substance react. In this case

Effects of Temperature‚ pH‚ Enzyme Concentration‚ and Substrate Concentration on Enzymatic Activity INTRODUCTION Enzymes‚ proteins that act as catalysts‚ are the most important type of protein[1]. Catalysts speed up chemical reactions and can go without being used up or changed [3] Without enzymes‚ the biochemical reactions that take place will react too slowly to keep up with the metabolic needs and the life functions of organisms. Catecholase is a reaction between oxygen and catechol

Title: “The Effect of Substrate Concentration‚ Enzyme Concentration‚ pH and Temperature on Enzyme Activity” Abstract: In the following experiments we will measure precise amounts of potato extract as well as Phenylthiourea‚ combined with or without deionized water and in some instances change the temperature and observe and record the reaction. We will also investigate the different levels of prepared pH on varying samples of the potato extract and the Phenylthiourea and record the results.

The effect of enzyme concentration‚ substrate concentration‚ pH‚ and temperature on the enzyme catalase. Introduction: Enzymes are biological catalysts; proteins and RNA. They are required for most biological reactions and they are highly specific. Each enzyme has an active site. The active site is the spot on the enzyme where a substrate fits in. Substrates binds with enzymes through the active site. Enzymes‚ being highly specific‚ only fit with one certain substrate. Enzymes and substrates

Reaction (PCR) and run on an agarose gel to detect the presence or absence of a transposable element known as an Alu element. The main purpose of this experiment was to use our class as a population‚ to test whether or not we were in Hardy-Weinberg Equilibrium. The Hardy Weinberg Law states that “in a large‚ random-mating population‚ the proportion of dominant and recessive genes present tends to remain constant from generation to generation unless outside forces act to change it” (Hardy-Weinberg law)

price above the equilibrium price reduces social welfare In a free market demand and supply alone determine the price. This means that quantity of demand and quantity of supply equate at this point is where the price is set which is therefore called equilibrium price. (Griffiths‚ 2011) Figure 1 illustrates where supply and demand intersect‚ this being the Equilibrium price and Quantity

JANUARY 6‚ 2011 SPECTROPHOTOMETRIC DETERMINATION OF THE EQUILIBRIUM CONSTANT OF A REACTION ABSTRACT The objective of the experiment was to determine the equilibrium constant of the reaction forming ferric thiocyanate through the use of Spectrophotometry. For the calibration‚ five standard solutions were prepared‚ then their respective absorbance values that were obtained through the use of the spectrophotometer‚ were plotted versus the concentration of the analyte so that a calibration curve would be

find the concentration (mole/dm3 (M)) of solute in a potato cell by using the process of osmosis and different concentrations of sucrose solution. Background information Osmosis is diffusion of water across a partially permeable membrane. It moves from a solution with less solute concentration (high water potential) to a solution with more solute concentration (low water potential). The one with a high water concentration is called a hypotonic solution and the low water concentration is called
