Answer:
Option-C
Explanation:
The process of muscle contraction and relaxation is very complex and involves the electrical signals, calcium ions, ATP, proteins- actin, myosin, troponin, tropomyosin, and many others.
The process of muscle contraction begins when the neural signals lead to the release of the sarcoplasmic calcium ions and then calcium binds to troponin and allows the binding of the tropomyosin and formation of cross-bridge.
The muscle relaxes when the signals from the brain stop the release of the calcium ions from the sarcoplasmic reticulum and the released ions are pumped back in the reticulum.
Thus, Option-C is the correct answer.
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.<span />
