Explanation:

Agonist muscles cause a particular movement, while antagonist muscles oppose that movement. For knee flexion, biceps femoris, semitendinosus are known agonists as they contract to bend the knee. Rectus femoris, vastus intermedius are quadriceps muscles which extend the knee and thus are antagonists to knee flexion.

Answer:

Agonist for knee flexion: Biceps Femoris, Semitendinosus
Antagonist to knee flexion: Rectus Femoris, Vastus Intermedius
