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

Gas Laws Name Institution The 3 Gas Laws Introduction The three gas laws include: Gay-Lussac’s law‚ Boyle’s law and Charles’ law. When combined with Avogadro’s law the three laws can be generalized by the ideal gas law. Gases possess observable properties which include‚ mass‚ pressure (P)‚ thermodynamic temperature (T) and volume (V). These properties are related to each other and the state of a gas is determined by their values. The three laws are derived from these properties. Discussion

GAS LAWS GROUP 1 Sheena Mae Agustin Hans Alcantara Renzo Bren Ado Miguel Afable Ron J Advincula De La Salle University - Dasmariñas Dasmariñas‚ Cavite Philippines ABSTRACT Gases behave in a similar way over a wide variety of conditions because to a good approximationthey all have molecules which are widely spaced‚ and nowadays the equation of state for an ideal gas isderived from kinetic theory. The combined gas law or general gas equation is formed by the combination of

Record the ammeter reading as the temperature increases 10°C before disconnecting the wire from the circuit and measuring the wire resistance immediately using the ohm meter. 4. Repeat procedure 4 when the temperature of the wire increases every 10°C until the highest temperature is reached and the measurements are recorded. Conclusion The hypothesis that when the temperature of a wire

These 2 micro-organisms‚ along with many other things circulate in the air within our environment. These micro-organisms then settle and become more prevalent in different areas.
