Question

1 multiple choice 2 points what part of the sliding filament model moves? axon sarcolema myosin actin

Explanation:

In the sliding filament model of muscle contraction, actin filaments slide over myosin filaments. The axon is part of a nerve cell, not directly involved in this model. The sarcolemma is the muscle cell membrane. Myosin has cross - bridges that interact with actin but it is the actin that moves relative to myosin during contraction.

Answer:

Actin
