Question
from question 3 to question 11.
3. How did you measure the rate of the reaction? How did you know if the reaction rate changed? 4. For each experiment, you initially prepared two tubes but only one was placed into the spectrophotometer. Why? s. Why did the reaction rate change when the amount of enzyme changed? 6. What was the optimal temperature for this enzyme? How did you arrive at your answer? Support with data. 7. What effect did temperature have on the reaction rate? Be sure to explain what caused the reaction rates to be similar at 0'C and 100°C. S. What was the optimal plH for this enzyme? How did you arrive at your answer? Support with data 9. What effect did pll have on the reaction rate? How did you arrive at your answer? Support with data? 10. What effect would the age of the "vegetable" have on the experiment? 11. If you used a "cooked vegetable" to prepare the enzyme, what results would you expect? Why?Explanation / Answer
3) Rate of reaction can be measured by the rate at which reactant is used up or product is formed. Change in concentration over time. if you change the temperature, add the catalyst , conc. of dissolved reactant reaction rate become change because all these factors affect the rate of reaction.
4) Because second tube is used as a control to see the effect of something u want to see in your sample so, second one is used as a measure.
5) because when you change the enzyme concentration , that amount of enzyme bind with your substrate and speeds up the rate of reaction. Enzymes contributes to overcome the threshold barries to acheive maximum velocity.
6) The optimum temperature for most of the animal/human enzyme is 37.5oC because As the temperature rises, reacting molecules have more and more kinetic energy. This increases the chances of a successful collision and so the rate increases. Above this temperature enzymes become denatured.
