Question
question 26 (2 points) muscle contraction requires that muscle thick and thin filaments generate enough atp to power the contraction repel and move away from each other recombine to form a new type of muscle filament switch places in the muscle become increasingly overlapped along their length
Muscle contraction occurs via the sliding - filament theory. Thick (myosin) and thin (actin) filaments slide past each other, increasing their overlap to shorten the muscle fiber. ATP is used for the process but is not generated by the filaments themselves. Filaments do not repel, recombine, or switch places.
