Conclusions From the Laboratory Work: Concentration of Enzymes


Words: 364 (2 pages)

Decision: Based on the consequences obtained from the experiment it can be concluded that the concentration of enzymes influences the rate of a chemical reaction. If enzyme concentration is decreased so the reaction rate will besides diminish. If there is sufficient enzyme to adhere with substrate so the reaction will continue fast and if there…

The Effect of Enzyme Concentration on Reaction Rate


Words: 1341 (6 pages)

Introduction Enzymes are said to be catalytic proteins which increases the rate of a chemical reaction without being altered in the procedure of that reaction. A substrate is a substance which an enzyme acts upon. No bond is formed between the enzyme and the substrate in the reaction therefore the enzyme goes back to its…

Determining the Concentration of a Solution – Application of Beer’s Law



Words: 864 (4 pages)

Purpose The purpose of this experiment was to produce a calibration curve of absorbance vs. concentration for NiSO4 and then to use this standard curve for determining concentration of an unknown solution of NiSO4. Introduction Many transition compounds exhibit colors due to d-d transition. The electrons from the partially filled d-subshells absorb a particular wavelength…

Effect of concentration of H2O2 on the enzyme catalase


Words: 2435 (10 pages)

Enzymes such as Catalase are large protein molecules that are found in living cells. They are used to speed up specific reactions in the cells. They are all specific as each enzyme just performs one particular reaction. In their globular structure, one or more polypeptide chains twist and fold, bringing together a small number of…

The Effect of Substrate Concentration on Enzyme Activity


Words: 1751 (8 pages)

Question What is the consequence of increasing the substrate concentration, as measured by thining the concentration of 3 % H peroxide in an aqueous solution ( 0.6 % , 1.2 % , 1.8 % 2.4 % and 3.0 % ) , on the rate of enzyme activity of the enzyme catalase, obtained fromBos primigenius (…

The effect of antibiotic concentration on bacterial growth


Words: 2038 (9 pages)

The effect of antibiotic concentration on bacterial growthIntroductionNull Hypothesis- Increasing the antibiotic concentration has no effect on bacterial growth. Experimental Hypothesis- Increasing the antibiotic concentration decreases bacterial growth.Scientific TheoryBacteria are prokaryotes and can be identified by their shape. Spherical bacteria are called cocci, rod shaped bacteria are called bacilli, spiral shaped bacteria are called spirilla…

Seller Concentration


Words: 1913 (8 pages)

Market structure plays an important role in any industry. Examining the market structure is essential for firms to perform well and behave rationally. The key characteristics of market structure include the number and size of firms, the existence and height barriers to entry and exit, and the degree of product differentiation. Seller concentration refers to…

Estimating Glucose Concentration in Solution


Words: 1798 (8 pages)

Introduction Glucose is very important in our daily lives. It gives us energy to carry out all of our activities. Cells in our bodies need glucose to respire and in the process release the energy we need. Glucose is also a type of carbohydrate. It has a chemical formula of C6H12O6 and is a monosaccharide…

It finds usage in Pharmaceutical Industry, Pollution suspension systems, Agro Chemicals, and Chemical Industry. There are many methods available for finding the Partition Coefficient, particularly Instrument methods like, Chromatography, Electrophoresis…

Harcourt-Essen Reaction




Words: 2298 (10 pages)

Aims: I aim to find out the order of reaction with respect to [H2O2] and [2I-]. I aim to find out the activation enthalpy of the reaction by finding the rate of reaction at different temperatures using the Arrhenius Equation. The experiment will go as follows: Into a conical flask put 15cm3 of distilled water…
