Web11. The number of correct statements amongst the given statements is: I. Cardiac muscles are striated and involuntary. II. Myosin head is an active ATPase enzyme. III. The neurotransmitter released at the neuromuscular junction is acetylcholine. IV. White muscle fibers depend on anaerobic process for energy. WebMyosin cross-bridges dissociate from actin following Mg2+-adenosine triphosphate (MgATP) binding. Myosin hydrolyses MgATP into inorganic phosphate (Pi) and Mg2+-adenosine diphosphate (ADP), and release of these hydrolysis products drives chemo-mechanical energy transitions within the cross-bridge cycle to power muscle contraction.
