| A researcher was investigating the substrate specificity of two different enzymes, X and Y, on the same substrate. Both the enzymes were subjected to treatment with either heat or an inhibitor which inhibits the enzyme activity. Following are the results obtained where |
| a=inhibitor treatment, b=heat treatment and c=control. |
 |
| Which of the following statements is correct? |
A) Only protein X is specific for the substrate, S.
B) Only protein Y is specific for the substrate, S.
C) Both X and Y are specific for the substrate, S.
D) Both X and Y are non-specific for the substrate, S.
Correct Answer: C
Solution :
Activity of both the enzymes is affected due to addition of inhibitor and heat treatment so both the enzymes are specific for substrate S.
