During periods of sustained demand and in the presence of sufficient nutrients muscle cells can increase in size When the size of muscle cells increases they will often develop additional nuclei in their intracellular environment Which of the following is the most likely explanation for the expression of additional nu clei in growing muscle cells A B C D The ATP molecules that are produced in the additional nuclei will be able to better sup port the increased energetic demands on the muscle cell as its size increases Additional nuclei allow subcellular components to continue to be sufficiently expressed and transferred across the cell even as the volume of the cell increases Nutrients entering the cells will be digested and recycled more quickly by the additional nuclei to better support the subcellular components in the cell as its size increases The addition of more nuclei to the cell will allow more genetic information to be stored in the cell and allow the cell to produce additional types of proteins as its size increases
