after a power stroke, the myosin head must detach from acting before another powerstroke can occur. what causes
kompoz [17]

The myosin head separates from actin as a result of ATP binding. The intrinsic ATPase activity of myosin then transforms ATP into ADP and Pi. The myosin head's angle is altered into a cocked state by the energy generated during ATP hydrolysis. The myosin head is now ready to move in the future.

The myosin protein is in a high-energy conformation when the head is cocked. At the end of the power stroke, the myosin head is in a low-energy position because this energy has been used up during the power stroke. ADP is released following the power stroke, but the cross-bridge is still there and actin and myosin are joined together.

Since ATP is readily available, the cross-bridge cycle can repeat, and muscular contraction can go on as long as ATP is there.

The elevated blood potassium prompts aldosterone discharge from the adrenal cortex. The aldosterone is foremost mineralocorticoid hormone which is a steroid hormone formed by the zona glomerulosa of the adrenal cortex in the adrenal gland however the adrenal cortex is the outside portion of the gland that yields hormones that are vivacious to life such as cortisol which aids control metabolic rate and helps the body react to anxiety and aldosterone which aids control blood pressure.
