Question

Will a skeletal muscle that is deprived of adequate ATP supplies sequester all free calcium ions?

Anonymous · Accepted Answer

A  skeletal   muscle  deprived  of  adequate  ATP  supplies  will   enter  a  state   where  actin   and  myosin  are  enable  to   separate   Actin   and  myosin  are  responsible  not  only  for  muscle   contracting  but  also  for  a  variety  of  movements  of  non  muscle  cell  including  cell   division. Most  skeletal  muscle   are  attached  to  bones  by   bundles    of  collagen   fiber.

The correct answer is that the skeletal muscle will enter a state wherein actin and myosin cannot separate. In the presence of adequate ATP, ATP will act to detach the myosin head to actin then ATP will be hydrolyzed to ADP then the myosin head will attach to actin. In the absence of adequate ATP, there will be no ATP to detach the myosin head to actin therefore the actin and myosin cannot separate and muscles will be contracted and stiff. This happens in ATP depletion and muscle stiffness in dead persons called rigor mortis.
