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

Do professional athletes get paid too much? In my personal opinion: No In this modern era this is an ethical issue that comes up more and more often. This has been brought up especially in times of economic hardship and the recession whereby families are really struggling to make ends meet with unemployment‚ delay of retirement and general reductions in disposable income. During this paper it shall be discussed how the ethical issue of high wages came about‚ why it is an issue‚ who is affected

My lab group studied the effect of PH on reaction rate/ enzyme activity measured by foam height. PH is the measure of the concentration of hydrogen ions in a solution. The higher the hydrogen ion concentration‚ the lower the pH. Every enzyme has an optimal PH‚ meaning they have a very small window in which they are most active. Our enzyme (potato smoothie) had an optimal PH of 7.0-7.5. We know this because we measured the enzyme’s reaction rate by measuring foam height. The largest foam height we

While some people might argue that this information should be fully disclosed‚ I believe that prior convictions should have no bearing on current accusations. First‚ everyone should be provided with impartial judgement. Second‚ you need evidence to convict. Finally‚ ex-criminals have a hard enough time going straight without prior records haunting them. First‚ perhaps the strongest reason to deter prior records becoming available

With many people today opting for some kind of sport as a hobby or following or supporting a team means that sport is a popular choice of interest‚ whether it be as an occupation‚ a means of spending leisure time‚ watching or taking part in it‚ making it a relevant topic to research in today ’s society.

Enzymes play a vital role in helping our body function. They act as biological catalysts and help speed up reactions that would otherwise take long periods of time to naturally occur. Enzymes help lower the activation energy required for the reactants to reach the transitional state from which then they can form products. However‚ enzymes do not change the free energy of the reaction. Enzyme’s ability to catalyze reactions comes from the shape of the active site on the enzyme. Enzymes are hyper-specific

The functions are contraction of uterine smooth muscle during labor. Contraction of myoepithelial cells around breast ducts and alveoli to stimulate milk flow and it is queried as to whether oxytocin release actually causes the onset of labor. Oxytocin primarily affects uterine smooth muscle - increasing both the frequency and duration of action potentials during uterine contractions. Oestrogen enhances the effects of oxytocin by lowering the membrane potential of smooth muscle cells. As the fetus

As an old saying goes‚ “a man who is contented will be always happy.” Involved in the world full of hundreds of thousands of substances‚ we must learn to be satisfied in case of being hurt by our greedy. In chapter 14 of Bible‚ among the fishermen were two men called James and John who were asked to launch out into the deep and let down their nets for a draught. Having finished as they were asked‚ they found that their nets were filled with fishes. When they had emptied the nets into the two boats

Are professional athletes overpaid? This question continues to permeate conversations from the board rooms to locker rooms; to street corners and beyond. How much is too much money for an athlete to earn. Folks will argue that the money could be spent on increasing teachers salaries as they are responsible for sculpting the minds of the American youth. Athletes make more money in one day than most Americans will make in a lifetime. New York Times best selling author David Epstein posed the following

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
