Enzyme Catalase Activity in Reaction with the Substrate Hydrogen Peroxide Abstract We performed these experiments to observe the effects of enzymes on the rate of reactions. We tested and compared the activity of the enzyme catalase on the substrate H2O2 in various states and percentages‚ and observed the absorption values of the enzyme-substrate relationship at different concentrations. Our results show that the more substrate available‚ the quicker the reaction will happen except in one test

My lab group studied the effect of PH on reaction rate/ enzyme activity measured by foam height. PH is the measure of the concentration of hydrogen ions in a solution. The higher the hydrogen ion concentration‚ the lower the pH. Every enzyme has an optimal PH‚ meaning they have a very small window in which they are most active. Our enzyme (potato smoothie) had an optimal PH of 7.0-7.5. We know this because we measured the enzyme’s reaction rate by measuring foam height. The largest foam height we

However‚ not all takers are fortunate enough to pass the exams and never have been any occurrence of 100% national passing rate throughout NLE’s history. Non passers may review and retake but some are faced with dilemmas that’ll make it even harder for them to cope up and pass the next time around. A total of

prediction. I have also noticed that the highest rate is at a slightly higher temperature than I expected‚ though this may be due to the large difference in temperature between each sample. As the temperature was increases the molecules were given more energy and move around in the solution quicker increasing the chances of collision‚ speeding up the brake down of starch. I had found that where the temperature was above 40Ëšc the enzyme did not work as efficiently‚ even with the extra

INVESTIGATE A FACTOR AFFECTING THE RATE OF PHOTOSYNTHESIS. Introduction Photosynthesis is a chemical reaction which takes place inside the green plants (plants with chlorophyll‚ a pigment found in chloroplasts which causes the colour of the plants and it is the main photosynthetic pigment) and light energy is converted into chemical energy. Carbon dioxide‚ water and sunlight is transformed into sugar an oxygen‚ which later will be used as energy for the plant. The chemical equation of photosynthesis

Factors affecting the rate of coastal erosion Rock types - Soft rocks like clay or mud‚ erode faster than hard rocks like granite. This is because hard rocks are more resistant to erosion. This means that the hard rock is left sticking out into the sea as a headland. The headland is now vulnerable to the force of destructive waves but shelters the bays close by from further erosion. Wave type - Destructive waves cause more erosion than constructive waves. This is because backwash is more powerful
