This experiment shows the effects of changing the pH level has on Catalase. As predicted‚ the farther away the pH levels got from the optimum pH (7.2)‚ the lower the reaction rate. At a pH of 7.2‚ the foam of the reaction measures 6cm. At a ph of 3 it measures 2.5 cm‚ at a pH of 5 it measures 2.75 cm‚ at ph 9 it measures 2.3 and at 11cm it measures 2cm. pH measures the hydrogen ion concentration of a substrate. By changing the pH of the catalase‚ the enzyme was denatured. Denaturing is the result

deadly and complicated diabetes is. When first diagnosed with diabetes patients may often be confused by how their lifestyle will have to change. Some patients may not even know how serious the complications may be. This information is to help not only the people who are affected by diabetes but also to inform everyone on how to help prevent the onset of diabetes. II. Background Data A. Statistics 1. “Total: 25.8 million people‚ or 8.3% of the U.S. population‚ have diabetes. Diagnosed: 18.8

“Due diligence” simply means taking all reasonable care to protect the well-being of employees or co-workers. It is the opposite of negligence. To meet the standard of due diligence‚ you must take all precautions that are reasonable in the circumstances so that you can carry out your work and your health and safety responsibilities. The single most frequent cause of accidents in the workplace is failing to take the time to think through the work‚ identify the hazards and deal with them. Due diligence

I was always thirsty and in need of a drink. After a while my mother decided to take me to the doctor’s office‚ where they did some blood testing to hopefully determine what was wrong with me. The results came back‚ and they said that I had Type 1 Diabetes. The immediately took me to the hospital‚ Childrens Hospital of Pittsburgh‚ where I was hooked up to an IV and stayed in the emergency room for an entire week. What happened would be something that changed my life from that moment forward.

Procedure: Part I: Titration with an Indicator 1. Fill the 50-milliliter buret with a 0.25 molar NaOH solution. 2. Record volume. 3. Measure out between 20 milliliters and 40 milliliters of the unknown HCl solution. 4. Record volume. 5. The amount of unknown HCl is then added to the 100-milliliter Erlenmeyer flask. 6. Add two drops of the indicator‚ phenolphthalein‚ to the acid in the flask. 7. Using the slider on the right hand side‚ add NaOH to the HCl in the Erlenmeyer flask (This action

Buffers‚ and pH‚ and Diffusion oh my The pH of a solution is the measure of the concentration of charged Hydrogen ions in that given solution. A solution with a pH lower than seven is considered to be acidic. A solution with a higher pH is a base. It is very important for organisms to maintain a stable pH. Biological molecules such as proteins function only at a certain pH level and any changes in pH can result in them not functioning properly. To maintain these constant pH levels‚ buffer solutions

analyzing pH it measures for the acidity or basicity of a solution. pH levels vary depending on the solution. The more acidic solutions would be juices and vinegar and cleaning materials would be basic. You can determine the purpose of solutions based on their acidity and basicity. We measure the pH of solutions on a scale with levels from 1-14. These levels may change if other solutions are added‚ we can tell what the pH will be based on its colour. Solutions called buffers change the pH levels of

health of mother and baby there are many conditions that women find themselves faced with during pregnancy such as gestational diabetes. Gestational diabetes is a conditions which develops during pregnancy. It occurs when the body is incapable of producing enough insulin to for the mother and fetus. If not properly managed it can cause adverse complications to the mother and the baby. Bassaw et al (2012) states “the main purpose of diagnosing gestational diabetes is to identify women at high risk of

the effects of an incorrect pH level. pH measures the concentration of hydronium ions and can be modeled by the function p(t) = −log10t. The variable t represents the amount of hydronium ions; p(t) gives the resulting pH level. Water at 25 degrees Celsius has a pH of 7. Anything that has a pH less than 7 is called acidic‚ a pH above 7 is basic‚ or alkaline. Seawater has a pH just more than 8‚ whereas lemonade has a pH of approximately 3. 1) Create a graph of the pH function either by hand or using

“Assess the extent to which religion produces social change” (33 marks) There is a great debate concerning the role of religion in social change. Whereas some sociologists believe that religion acts as a conservative force‚ thus inhibiting social change whether that is positive or negative‚ others believe that religion is a radical force and a major contributor to social change. As expected many sociologists have taken the middle ground‚ arguing that religion can be both encouraging and preventing
