QUESTION
Callipyge lamb contains?
OPTIONS
(A) More calpastatin
(B) Less calpastatin
(C) More calpain
(D) Less calpain
ANSWER
(A) More calpastatin
EXPLANATION
Callipyge lambs have markedly elevated calpastatin activity in affected muscles. Calpastatin inhibits calpains, reducing postmortem proteolysis and contributing to the characteristic toughness of callipyge meat. Thus, increased rather than decreased calpastatin is the defining feature, making option (A) correct.
