Question

In the sliding-filament model, what would happen if myosin did not attach to actin filaments

Answer 1

The sliding filament theory refers to the mechanism in which contraction takes place due to the attachment of myosin to actin, producing cross-bridges that produce filament movement. The actin comprises globin head that possesses receptors for the attachment of myosin. In case, if actin do not get combined with myosin it will result in permanent muscle relaxation.

Answer 2

Here is the answer. In the sliding-filament model, if myosin did not attach to actin filaments, what happens is that, the muscle would be permanently relaxed. Myosins work with actins and these are motor proteins. Hope this is the answer that you are looking for.
