Vedclass · Answer

(A) Muscle contraction is primarily driven by the interaction between two key contractile proteins: $Actin$ and $Myosin$.$Actin$ forms the thin filaments,while $Myosin$ forms the thick filaments.These proteins slide past each other during the contraction process,known as the sliding filament theory.$Tubulin$ is a structural protein involved in the formation of microtubules,not muscle contraction.Therefore,both $Actin$ and $Myosin$ are contractile proteins,making the correct choice 'All of the above'.
