Title: During muscle contraction, myosin cross bridges to attach to which active sites? Post by: smmoh4 on Oct 14, 2012 a. Z discs
b. thick filaments c. myosin filaments d. actin filaments i am confused with Sliding filament theory of contraction which states that: during contraction the thin filaments slide past the thick ones so that the actin and myosin filaments overlap to a greater degree. Is it D? thanks. Title: During muscle contraction, myosin cross bridges to attach to which active sites? Post by: smn on Oct 14, 2012 a
