BMD (2,3-butanedione 2-monoximime) inhibits myosin, such that ATP can bind to myosin but myosin is unable to hydrolyze the bound ATP. What effect would BMD have on the cross bridge cycle?
Tropomyosin would not move, and the active sites on actin would not be exposed.
Myosin heads would remain detached, unable to cock.
Myosin heads would remain attached to actin, unable to perform the power stroke.
Myosin heads would remain attached to actin, unable to detach.
