Which molecule prevents a muscle contraction from occurring when the muscle is at rest?
AysviL [449]

Troponin-tropomyosin molecules prevents a muscle contraction from occurring when the muscle is at rest.

<h3>What is muscle contraction?</h3>

The activation of tension-producing regions within muscle cells results in muscular contraction. Because muscle tension can be created without changes in muscle length, such as when holding something heavy in the same position, muscle contraction does not always imply muscle shortening in physiology. Muscle relaxation, or the return of the muscular fibers to their low tension-generating state, occurs after a muscle contraction has finished.

Both length and tension can be used to characterize muscle contractions. If the muscle tension varies but the muscle length doesn't, the muscle contraction is said to be isometric. A muscle contraction is isotonic, however, if the tension in the muscle remains constant during the contraction.
