Final Answer :
True
Explanation :
A muscle's role as an agonist or antagonist is dependent on the action being performed. It can act as an agonist (prime mover) in one action and as an antagonist (opposes the action) in another action. For example, the biceps muscle can be an agonist in elbow flexion (bending) and an antagonist in elbow extension (straightening).
