Question

question 18 (2 points) listen muscle contraction requires that muscle thick and thin filaments generate enough atp to power the contraction become increasingly overlapped along their length switch places in the muscle repel and move away from each other recombine to form a new type of muscle filament

Explanation:

Muscle contraction occurs via the sliding - filament theory. During this process, the thick (myosin) and thin (actin) filaments slide past each other, increasing their overlap. ATP is used for the process but is not generated by the filaments themselves. The filaments do not switch places, repel each other, or recombine to form a new type of filament.

Answer:

B. become increasingly overlapped along their length
