Question

Quizplus · Accepted Answer

When a skeletal muscle is deprived of adequate ATP supplies, it will enter a state where actin and myosin are unable to separate. This is known as rigor mortis and occurs after death, when the body's ATP supplies are exhausted. In this state, the muscle becomes stiff and rigid, as the actin and myosin filaments remain locked together due to the lack of ATP to break the cross-bridges. The other options are incorrect, as the muscle will not immediately relax or release actin-myosin bonds without ATP. It also will not fire more action potentials than usual or sequester all free calcium ions into the sarcoplasmic reticulum without ATP.
