Question

If a disorder makes it impossible for ATP to bind to the myosin head, which symptom would a person suffering from this disorder most likely display?

Answer 1

If a disorder prevents ATP from binding to the myosin head, it would likely lead to muscle stiffness or rigidity. Without ATP binding, the myosin heads cannot detach from the actin filaments, resulting in impaired muscle relaxation and increased muscle tension. This symptom is commonly seen in conditions like stiff-person syndrome or certain forms of muscle rigidity disorders.
