Q1. Consider the two statements:
Assertion (A):  It is better to consider the respiratory pathway as an amphibolic pathway rather than as a catabolic one.
Reason (R):   The respiratory pathway is involved in both anabolism and catabolism.

 

  • Both(A)and(R)are True and(R)is the correct explanation of(A).
  • Both(A)and(R)are True but(R)is not the correct explanation of(A).
  • (A)is True but(R)is False.
