Effects of Temperature on Enzyme Biology Introduction In order to understand the activity of enzymes at different temperatures the ability of the enzyme to function can be measured. This is important in many applications such as Polymerase Chain Reaction for forensics as well as genetics research where manipulation of temperature-dependent enzymes allows for replication of DNA segments. Bennett states‚ “when the energy - measured

Acid and Bases 1 Determining Acids and Bases SNC-2D1 April 02‚ 2013 Acid and Bases 2 Purpose The purpose of this chemistry lab is to investigate and find patterns/tendencies between substances Introduction An acid is a solution that has more free hydrogen ions (H + ) than hydroxyl ions (OH - ) and a pH less than 7. A base is a solution that has less free hydrogen ions (H + ) than hydroxyl ions (OH - ) and a pH of more than 7. In the late 1800s‚ the Swedish scientist Svante

RESULTS AND DISCUSSION E. coli and S. aureus were tested to determine effectiveness of photodynamic inactivation with the use of methylene blue as photosensitizer and blue LED as alternative light source. Table 1 shows the resulting number of colonies for each replicate of every treatment per bacteria tested. Each of the treatments was averaged to get the mean number of colonies per treatment. All experimental setups were produced in quintuplicate‚ however only three of the five replicates were

Enzyme activity The introduction is a statement of the subject and objectives of the experiment and presents your hypothesis. Relevant background information (appropriately referenced) is given in sufficient detail that a person unfamiliar with the topic can understand the nature of the experiment. A good introduction is clear and concise. Carbohydrates and proteins should be explained in terms of their structure and major functions in cells. Your intro should end with a brief overview of the amylase

gain from the pictures taken at the scene? The v-shaped pattern often occurs in the area where a fire originated‚ so it is possible that the space heater was the fire of origin (tests needs to be run to confirm). The crazed glass (by lab results) indicated that crazing is the result of rapid cooling of hot glass by the application of water. The protected surface shows there was an object on the floor protecting the area‚ and there is the shape of a body that was there during the fire

Computer Enzyme Action: Testing Catalase Activity 6A H2O2 is toxic to most living organisms. Many organisms are capable of enzymatically destroying the H2O2 before it can do much damage. H2O2 can be converted to oxygen and water‚ as follows: 2 H2O2 → 2 H2O + O2 Although this reaction occurs spontaneously‚ enzymes increase the rate considerably. At least two different enzymes are known to catalyze this reaction: catalase‚ found in animals and protists‚ and peroxidase‚ found in plants. A great

The purpose of having a control when doing a lab is because it is the part that is already known and not likely to change. It is always important to have a stable variable in any experiment you do. This also helps with overlooking hidden variables so you can compare how the organisms in the control behaved differently from those in the experimental situation. The purpose of having multiple variables is to compare the difference between the outcomes with each of the different variables. It is important

The Effect Of Enzyme Concentration On Enzyme Activity The pancreatic duct in individuals who have cystic fibrosis frequently becomes blocked‚ reducing or preventing the release of pancreatic enzymes into the small intestine. The aim of this activity is to investigate the effect of a reduction in enzyme concentration on the rate of reaction‚ in this case the breakdown of protein by protease enzymes. Aim – Milk powder contains a white protein called casein. A white suspension of
