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

Picture of Dorian Gray‚ Lady Windermere’s Fan‚ and The Importance of Being Earnest seem quite disparate. The first is horror‚ while the latter two are comedies; the first is a novel‚ while the latter two are plays; the list of the differences between the works could continue. The striking thing about these works however‚ is their unified theme. Wilde uses the symbolism in each work—images of self in The Picture of Dorian Gray‚ the fan in Lady Windermere’s Fan‚ and the use of names in The Importance

World of Warcraft is a game that has captivated the hearts and computers of millions of people worldwide. No other game has brought such depth and intricacies into the world of online gaming‚ and no other game has brought such a controversial fan-base. Although one may proclaim to be a gamer and may play every day with friends‚ whether online or not‚ if that gamer does not play World of Warcraft‚ you can bet that gamer has criticized those who have; World of Warcraft players have become the archetype

A critical point happens when a substance has a high enough temperature and pressure that both liquid and gas can exist at the same time. This state is called a critical point. Now‚ when a state of matter changes from one state to another is called a phase shift. Phase shifts are extremely important and most commonly observe phase shifts daily. For an example‚ when water freezes into ice‚ or the water in the shower turns to steam. To begin to start describing how a phase shift works we must understand

CP2085 Effect of Temperature‚ Study and Measure of Enzymes Activity Abstract This experiment investigates the effect that temperature has on the rate of activity of enzyme β-galactosidase and also the rate of β-galactosidase activity in different concentration of substrate over time. Ο-nitrophenylgalactoside (ONPG) is used as a substrate for β-galactosidase. A spectrophotometer is used to detect the change in colour of the substrate. Results show that increase in temperature up to 50oC speeds

The Roman Republic did well in some ways they controlled their government‚ while in others they didn’t do so well. The Roman Republic established a republic‚ citizens elected representatives to rule on their behalf in this type of government. The Roman Republic was a very advanced civilization. The Roman people elected Consuls‚ who ruled for a short period of time. I would give the Roman Republic a grade of A for providing public services because they met the common good by providing fresh water

Effect of Osmotic Stress and Temperature on Microbial Growth BIO 3400-002L – Microbiology Lab 1 Effect of Osmotic Stress and Temperature on Microbial Growth Luiz Felipe Isidoro ABSTRACT Evolution allowed primitive forms of life to develop proteins and enzymes that made it possible for life to evolve under environments with hostile conditions‚ such as high salt and heat. More specifically‚ some bacteria selected genes that code for peptides with stronger intermolecular forces‚ coping

from the wire using the tips of the paper knife. Measure the resistance of the wire using the ohm setting on the multimeter. 2. Connect the batteries in series using the jumper wires to produce 4.5 V. The ammeter‚ battery and wire wound around the pipe should be connected as shown in figure 1. 3. Record the initial current reading shown on the ammeter. As the current flows in the magnet wire‚ the temperature of the wire will be increasing. Measure the temperature using the infrared

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
