Also‚ to understand that the rate of the reaction can be saturated and it depends on the concentration of the substrate (when [S] [E]). Specifically‚ we studied the kinetics of the enzyme lactase which is an enzyme that catalyzes the hydrolysis of lactose sugar into glucose and galactose

Formal Lab Report #1 I. Basics Title of the Experiment: The Empirical Formula of an Oxide Authors: Section Number: Chemistry Location and Date II. Abstract The aim in this lab was to determine the empirical formula of an oxide of magnesium through combustion in air. This was achieved by heating an established mass of magnesium in air inside of a crucible‚ ultimately attaining a compound that contained Mg and O. The major result of the experiment was the empirical formula of the oxide of magnesium

Metabolic Syndrome: A Precursor of Heart Disease In 1988‚ Dr. Gerald Reaven was awarded the Banting Medal for Scientific Research by the American Diabetes Association and introduced the term Syndrome X to the medical community. According to Dr. Reaven‚ “Syndrome X is a simple way to refer to a cluster of changes that encourage the onset and development of heart disease.” (Reaven‚ 2000‚ pg. 40) The medical terms Syndrome X‚ Insulin Resistance (IR)‚ or Metabolic Syndrome (MetS) have been used interchangeably

IB Chemistry Experiment 4 Composition of a Post-1983 Penny Lab Report Background: Through the use of percent composition one can easily find out how much of a certain element is in a compound or an item such as a post-1983 penny. The experiment will be using HCl a strong acid to dissolve all the zinc inside the outer copper shell. The reaction follows as such; Zn+2HCLZnCl2+H2‚ but there will be no reaction with copper. The portion that will be measured is the mass of copper left after all of

peroxidase and its reaction rate in seconds‚ we were able to see that as the amount of enzyme increased the catalytic reaction also increased. The optimal amount of peroxidase concentration to be used in the subsequent experiments was determined to be 1.0 mL. Any amount above this would have caused the rate of absorbance to be too fast‚ making it too difficult to get accurate readings. Any amount below this would not have produced a reaction “at an appreciable rate.” (Dolphin‚ Vleck‚ Colbert and

The Effect of Substrate Concentration on Initial Reaction Rate The purpose of this study is to identify the relationship between substrate concentration and initial reaction rate provided that substrate concentration is much greater than enzyme concentration. Enzymes are essential to life as they are required for many vital metabolic reactions to occur. To adequately explain the properties of enzymes‚ it is assumed that an enzyme-controlled reaction takes place through an enzyme-substrate

4. Results No hypotheses in the discussion section were necessarily falsified‚ but some broad statements were made. For example; “Culture conditions obviously influence the outcome of adaptive evolution.” This statement implies that they have extensive knowledge on all the different aspects of evolution. Many scientists today will admit that we do not fully understand evolution and all the factors involved. To say that the conditions ‘obviously’ influenced that outcome is too broad of a statement

Increased production of CO2 is a result of increased temperatures acceleration of the rate of fermentation. Abstract: We have tested the affects of increased temperature above room temperature on the rate of fermentation of yeast. We had 6 flasks filled with 6mL DI water‚ 2mL Yeast suspension and 6mL glucose of which 3 were at 25°C and 3 were at 37°C. The flasks at 37°C had each mixture pre-heated at 37°C for 2 minutes before being combined and then added to the flask where it was put into the

Antibiotic Lab Report By: Sierra Toll Hour: 6 Title: The effects of antibiotics on the growth of Escherichia Coli Problem: How do antibiotics affect the growth of E coli? Hypothesis: If Penicillin is applied to the bacteria‚ then the zone of inhibition will be larger. Background: The purpose of this lab was to see how effective a certain antibiotic is to kill E coli. The lab tested three antibiotics‚ Penicillin‚ Erythromycin‚ and Neomycin. The zone of inhibition‚ which is the amount of space
