Given below are two statements: one is labelled as Assertion (A) and the other is labelled as Reason (R). Assertion (A): Streptokinase acts by competitively inhibiting the enzyme responsible for cholesterol synthesis. Reason (R): Streptokinase is administered to patients who have undergone myocardial infarction to remove clots from blood vessels. In the light of the above statements, choose the most appropriate answe
Options
- ABoth (A) and (R) are correct and (R) is the correct explanation of (A)
- BBoth (A) and (R) are correct but (R) is not the correct explanation of (A)
- C(A) is correct but (R) is not correct
- D(A) is not correct but (R) is correct
Correct answer
D. (A) is not correct but (R) is correct
Step-by-step solution
Assertion (A) is not correct because streptokinase acts as a 'clot buster' to dissolve blood clots. The competitive inhibition of the enzyme responsible for cholesterol synthesis is the mechanism of action of statins, not streptokinase. Reason (R) is correct because streptokinase, produced by the bacterium Streptococcus and modified by genetic engineering, is clinically administered to patients who have suffered a myocardial infarction to remove clots from their blood vessels. Therefore, (A) is not correct but (R)
