if antimicrobial concentration increases‚ then the zone of inhibition will increase because the higher the concentration‚ the more the antimicrobial will disinfect the area of bacteria and thus the zone of inhibition will increase.The results of the lab do support my hypothesis. Paragraph 2: My antimicrobial was bleach. Bleach contains hypochlorous acid which “causes bacterial proteins to unfold and stick to one another‚ making them nonfunctional and leading to cell death”(publications.nigms.nih.gov)

Enzymes are responsible for multiple reactions that take place naturally in the living organisms. The purpose of the enzymes lab was to investigate how the enzymes play a role in a reaction‚ affecting the rate of reaction (ROR). Interestingly‚ we tested how the enzymes affect the reaction rate at multiple temperatures (0‚ 23‚ 37‚ 50‚ 70‚ and 95 C). It was predicted that an increase in temperature will elevate the thermal activity of substrate which increases the chances the substrate molecules will

In conclusion‚ even though the lab procedure is not about moles‚ most of the calculations are and this is one lab where the concept of

Determining the Catalytic Properties of the Enzyme Peroxidase Extracted from a Turnip Under the Conditions of Temperature‚ pH‚ Boiling and Competitive Inhibitors By Robin Caserta BIO 101 September 30‚ 2013 ABSTRACT The enzyme‚ peroxidase‚ extracted from a turnip was tested for its efficiency in binding to its substrate and its stability under several conditions. To do this‚ we tested effects on peroxidase activity‚ first‚ with different amounts of the enzyme‚ next at temperatures of

Title: Enzyme Catalysis of Hydrogen Peroxide by Catalase Problem and Objectives: How do different temperatures and different levels of pH affect the reaction rate of the enzymes in chicken liver? Demonstrate the activity of an enzyme in living tissue‚ observe the effects of changes in temperature and pH on the activity of an enzyme‚ perform analyses for the presence of an enzyme in tissues‚ and analyzing relationships between environmental conditions and enzyme activity. Background: Cells produce

The Determination of the Concentration of Hard Water Ions by the Titration of EDTA By Hannah Denby Lab partners: Heidi Kiziah‚ Leonie Hamel University of Central Florida‚ CHM 2046L December 3rd‚ 2015 Abstract. The “hardness” of water is a common dilemma attributed by high concentrations of metals such as calcium and magnesium. This is a result of the properties of water; because it is a good solvent‚ impurities are easily dissolved. As water moves through soil and rock‚ it dissolves minute amounts

Thermal physics is the combined study of thermodynamics‚ statistical mechanics‚ and kinetic theory. This practical is done to measure the temperature drop of water over a period of time (30 minutes). Research question- What is the rate of temperature change over a period of 30 minutes? Independent variable- time Dependent variable- the temperature of water Controlled variables- the amount of water in the calorimeter - The stop watch

It was hypothesized that if the animal was larger‚ then it would have larger hemoglobin. It was thought that larger mammals would need more oxygen-rich hemoglobin to support healthy function. This lab did not support this hypothesis. The results in table 1 displayed that the hemoglobin of all mammalian samples traveled about the same distance. This trend can be seen in graph 1 as the mammalian hemoglobin samples migrated the same distance. Because the proteins traveled around the same distance it
