The correct answer is that "t<span>roponin holds the tropomyosin in place on the actin".
In excitation-contraction coupling, tropomyosin prevents the interaction between actin and myosin in resting muscles. In the event of excitation, there is release of calcium from the sarcoplasmic reticulum wherein the troponin will bind this calcium and will release tropomyosin and expose myosin enabling it to attach to actin and therefore facilitating muscle contraction.</span>
The answer to this question would be lysosome.
Build up of waste material mostly caused by disease in the enzyme that digests the material. Lysosome would be the organ that will hold the material until it was digested. Since it won't digest, the material will be in lysosome forever. The disease itself called lysosomal storage disorder, which was part of the inborn error of metabolism.
