initial rate of reaction. I will measure the effect of the enzyme in 5 different concentrations against the controlled variable of the reactant. The enzyme which will be used is different concentrations of potato and the reactant used will be Hydrogen Peroxide. Hydrogen Peroxide which will be the buffer solution is a PH of 7.2. My hypothesis for the experiment is that as the concentration of the enzyme is increased the rate of reaction will be increased‚ producing oxygen at a faster rate. The results

The readings were taken before exercise‚ during exercise and after exercise. Blood pressure is defined as the amount of pressure exerted on the vessels walls‚ during blood flow. Blood pressure can be measured using a sphygmomanometer. The upper value indicates the
