table of results. The graph shows that the highest rate of reaction is at pH 7. This therefore supports my theory that at pH 7 the rate of reaction will be highest. This relate to other resources‚ such as books and the internet‚ which show that the optimum pH value for catalase is pH7‚ therefore there is no difference between the optimum pH and the pH used in the experiment‚ hence the enzyme structure is not affected by the pH and is most active. However the graph inadequately supports the second

The plant was grown in solutions of pH 3 and 5.6 and the control was a solution of pH 7. This was done over 3 weeks and the plants were measured every day at the same time. The results of growth from day 4 to day 10 were recorded and they show that the plant grew the most in the pH of 5.6 at first but by the 10th day‚ the plant in the solution of pH 7 had grown the most and the plant in the pH 5.6 solution survived and was not far behind but the solution with pH 3 died after the 6th day. Soon after

ABSTRACT. The regulation of internal pH is a physiological function of major importance for all organisms. The quantity pH is intended to be a measure of the activity of hydrogen ions in solution. Buffers‚ on the other hand‚ are solutions containing a substantial concentration of both

Did the pH level of the blood change at all during normal breathing? If so‚ how? No‚ it remained constant at 7.38 3. Was the pH level always within the “normal” range for the human body? Yes‚ the pH level remained normal within 7.35 and 7.45 4. Did the PCO2 level change during the course of normal breathing?

10. Tubes 2‚ 6‚ and 7 showed the effect of pH on amylase activity. The results of this experiment indicate that the activity maximum of amylase is at pH 7.0‚ whereas pH 2.0 and pH 9.0 demonstrated very little activity. In this experiment‚ pH 7.0 showed the highest level of amylase activity. Tube 3 showed that amylase did not contain maltose contamination. Tubes 3‚ 4‚ and 5 showed that water had no starch or maltose contamination. Tube 3 directly showed that water did not have maltose or starch contamination

suitable reference electrode and a sensitive potentiometer (a pH meter) may be advantageous. THEORY Any acid-base titration may be conducted potentiometrically. Two electrodes‚ after calibration [to relate potential in millivolts (mV) to a pH value] are immersed in a solution of the analyte. One is an indicator electrode‚ selective for H3O+ and the other a stable reference electrode. The potential difference‚ which after calibration is pH‚ is measured after the successive addition of known increments

Activity from pH and Concentration Abstract Enzymes are the key to many of the chemical reactions that our bodies depend on to live. Without enzymes‚ we would not exist. These biological catalysts speed up the reactions as well as reduce the amount of activation energy needed to complete the process. Knowing how important enzymes are to us‚ it is important to realize what they require to function. They need select conditions and rates to work right. These conditions can range from what level of pH to use
