An Investigation Into The Effect Of PH On The Activity Of Potato Tissue Catalase Aim The aim of my investigation is to see how pH affects the activity of potato tissue catalase‚ during the decomposition of hydrogen peroxide to produce water and oxygen. Catalase + 2H2O2 Catalase + 2H2O +O2 Catalase + Hydrogen Peroxide Catalase + Water + Oxygen Independent Variable The independent variable in this investigation is pH. Each individual enzyme has it’s own pH characteristic

and the density of mercury is 13 600 kg m-3: Answer: Atmospheric pressure = 76 cm Hg State the answer in Pascal: P = hρg = 0.76(13 600)(10) = 103 360 Pa 3.3.2 Gas Pressure • Gas pressure can be measured using manometers and Bourdon gauges. Manometer Bourdon gauge In manometers‚ pressure can be calculated based on pressure equilibrium. For example: Pressure at point A = Pressure at point C Gas pressure = Atmospheric pressure + hρg Chapter 3: Forces and Pressure Page 2 of 8 Hoo

Set-up: Put 5 NaOH pellets into an Eppendorf tube. Place in inverted into a testtube. Place a layer of netting over it. Put the mealworm into the test tube. Put into water bath. Make sure that water level is higher than worms can reach. Set up respirometer and connect to test tube when temp. stabilises. c) Record original volume reading of water in syringe‚ then every minute‚ record‚ the rate of decrement. d) Calculate rate of O2 consumption Additional Details per gram mass. And finally‚

Abstract The characteristics associated with water and air flowing vertically upwards was investigated through a bed of coarse ballotini (glass beads with a nominal diameter of 485 microns).Different flow rates for water and air is applied to determine the pressure drop and differentiate between the fixed bed and the fluidized bed characteristics. Also the measured onset of fluidization was compared with the predicted one. From this experiment it was obtained thatthe pressure drop increase as increasing
