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

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

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

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

The ginger root is from the plant zingiber officonate. It is from the same plant family as tumeric‚ a commonly used cooking spice. It has many uses in cooking and homeopathic medicine. Ginger root is grown in warmer climates‚ and used in landscaping as well as harvested in bulk. Ginger root is an herb. Ginger root is also known as several other names including amomum zingiber‚ ardraka‚ cochin ginger‚ gingembre‚ gan-jiang‚ sheng-jiang‚ and black ginger. First cultivated in South Asia and

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
