Given below are two statements: one is labelled as Assertion (A) and the other is labelled as Reason (R). Assertion (A): Patients who have undergone myocardial infarction are often treated with an enzyme produced by the bacterium Streptococcus. Reason (R): This enzyme acts as a competitive inhibitor for the enzyme responsible for cholesterol synthesis, thereby clearing the blood vessels. In the light of the above sta
Options
- ABoth (A) and (R) are true and (R) is the correct explanation of (A)
- B(A) is true but (R) is false
- CBoth (A) and (R) are true but (R) is not the correct explanation of (A)
- D(A) is false but (R) is true
Correct answer
B. (A) is true but (R) is false
Step-by-step solution
Assertion (A) is true because patients who have undergone myocardial infarction are treated with streptokinase, an enzyme produced by the bacterium Streptococcus, which acts as a 'clot buster'. Reason (R) is false because streptokinase works by removing clots from the blood vessels. It is statins (produced by the yeast Monascus purpureus) that act as competitive inhibitors for the enzyme responsible for cholesterol synthesis. Answer: (A) is true but (R) is false
