Zoology - Digestion and Absorption Question with Solution | TestHub
A set oftest tubes having same temperature but different pH were setup to conduct an experiment. To each of the tubes, starch and amylase were added in a mix of sterile water. The concentration was kept the same. The following table notes the reaction completion time for each of the six tubes.
| pH | ||||||
| Time taken to complete in seconds(s). |
Using the above data, determine the pH where amylase has shown highest rate of activity.
Options:
Answer:
Solution:
Enzymes are biocatalyst that help in speeding up the reaction rate exponentially. Temperature,, substrate concentration are few of the factors that affect the activity of the enzyme. These molecules shows highest activity work in a particularcalled as optimum. Below or above that pH range the enzyme activity will reduce or become inactive. Since the enzyme amylase took least time to break starch in the range ofcompared to other pH values, it is showing highest activity at pH. Thus, pHis the optimum.
