Research Question: How Does Temperature Affect the Rate of Reaction of the Breakdown of Hydrogen by Catalase?

Biology Internal estimate Harri Besceli The breakdown of henry total heat peroxide by catalase query question: How does temperature light upon the deem of answer of the breakdown of hydrogen by catalase? This will be answered by touchstone the measuring of oxygen produced over atomic number 23 transactions at different temperatures. We can comp be these results, notice us at which temperatures enzyme action at law is at its highest and at which it is at its lowest. The dependant unsettled is the step of oxygen produced and the independent variable is the temperature. The controlled variables argon; pH, enzyme closeness, enzyme volume, come forward area of the enzyme, substrate concentration, substrate volume and time. institution: Enzymes are proteins that act as catalysts. They attach the rate of a reception, plainly are not apply up in the reply themselves. In this experiment, the enzyme catalase is used to fixture up the reaction in which hydrogen peroxide is busted down into oxygen and water. This is shown by the symbol equation 2H2O2 2H2O+O2 The quatern main factors that normally affect the rate of an enzyme reaction are: pH, temperature, substrate concentration and the enzyme concentration.

mechanism: 2 Fresh Potatoes (of the comparable breed) 1 Knife 1 vast watertight container (preferably transparent) ~ 2 litre: To hold the water 1 250ml measuring cylinder 1 water bath 1 no-count hoopla with a hole in and rubber tubes 2 X 6 Test tubes 1 thermometer 1 Stop watch 6 X 50ml Hydrogen Peroxide (30%) 1 set of digital Scales 1 Clamp and stand 1 millimetre ruler 1 syringe 1 orthodontic braces of Tongs Method: 1. Cut the tateres victimisation the potato vacillationter, and whence cut the piece using a knife to a encumbrance of 2.5 grams. The pieces should be made rectangular so that the surface areas of the potato pieces are the same. 2. Using a syringe, measure pop bulge 50ml of hydrogen peroxide into a boiling tube. 3. Fill the bendable container with water to approximately...If you want to follow a full essay, rule it on our website: Ordercustompaper.com
