What do skeletal muscle contractions share in common with smooth muscle
contractions?
What do skeletal muscle contractions share in common with smooth muscle
contractions?
Both types of contractions consume very little ATP.
Both types of contractions generate little force or a weak force.
Both types of contractions do not require calcium ions for a contraction to occur.
Both types of contractions result from thick and thin filaments sliding past one
another.
