Effects of Temperature and pH on Catalase Activity INTRODUCTION Enzymes are organic catalysts that spur metabolic reactions. The presence of an enzyme within a cell is essential in order for any sort of reaction to take place. All enzymes are complex proteins that act in an organism’s closely controlled internal environment. In such a homeostatic environment‚ the temperature and the pH (concentration of hydrogen ions)‚ remain within a fairly narrow range. Extreme variations in pH and temperature

The negative effects of cell phones With the increasing popularity of cell phones comes many adverse effects not only on a social level but also on our health. Many of us can’t imagine a day without our cell phone but by Are we losing the ability to communicate face to face? How tragic it is to hear bout accidents caused by talking and texting while driving. We are easily convinced that we need new phones with new features but neglect the fact that the old phones that we dispose

Aim: To find the effect of temperature on enzymes‚ using a potato as a catalyst. The source of catalase is in the potato cells. 2H2O2 → O2 + H2O Planning: Introduction: An Enzyme is any one of many specialised organic substances‚ composed of polymers of amino acids‚ that act as catalysts to regulate the speed of the many chemical reactions involved in the metabolism of living organisms Enzymes are classified into several broad categories‚ such as hydrolytic‚ oxidising‚ and reducing‚ depending

were living in the time periods before the 90s‚ then we would be living in a generation in which no one would have come close to guessing that cell phones would be a vital source in living in these modern times. Who would have guessed that cell phones would start a massive epidemic to control the minds of the young generation? Who would have guessed that cell phones would be a major impact on how relationships are formed‚ destroyed‚ and kept together? Who would have guessed that these convenient devices

Effect of Temperature ( C ͦ) on Enzyme Catalase Activity in potato Aim: To investigate the Effect of temperature (10‚ 37‚ 60) Celsius (C ͦ) on enzyme catalase activity in potato using 2% of hydrogen peroxide (H202) as the substrate measuring the height (cm) of oxygen gas (bubbles) and calculating the volume of oxygen bubbles produced (cm3) Introduction: Enzymes are biological catalysts that speed up metabolic reactions without being affected. They lower the activation energy needed to start

make a task easier. A cell phone is a type of technology that is a common thing to see in everyday life. The world and the people in it have gotten used to this technology. Cell phones are making the lives of an estimated two hundred sixty five million Americans (Natterson 103) and three billion worldwide (Natterson 103)‚ easier. As useful as cell phones may be‚ there are negative effects in over using cell phones. Cell phone technology was first developed in the 1980’s‚ but cell phones became common

The Effects of Cell Phone Use From now on‚ people will rely on phones more and more. A great many reasons lead to Cell Phone Use‚ I just list 3 main reasons. The first reason is that we used most of time going for working in fast-paced modern life‚ So we spent that time easily to watch movies‚ read news‚ chatting‚ and play games by phones‚ not only waiting. The second reason is that we can acquire a great many knowledge from web by phones. The last reason is that phones can bridge gap

The effect of cell phones on health! Carrying expensive cell phones in our pocket for pleasure and purposely exposing it in front of our buddy does wonders to our reputation and personality. Everyone adores having a cell phone in this era. Particularly‚ we youngsters set upon moving with cell phones to schools and colleges. It’s good to be a part of assortments of technological world. But the growing technology is likely to threaten the life of people by giving out detrimental radiations. Yes‚

Aim: The aim of the experiment is to test the effect temperature has on the activity of the enzyme rennin. Hypothesis: I believe the rate of reaction will speed up as the temperature increases until it reaches about 37oC‚ which is the body temperature‚ where it will begin to slow down and stop reacting. I believe this will occur because enzymes have a temperature range at which they work best in and once the temperature goes out of this range the enzyme will stop working. Introduction:Enzymes are
