Final answer:
The cells in question are skeletal muscle fibers, which are multinucleated, aiding in muscle hypertrophy by efficiently producing proteins needed for muscle growth.
Step-by-step explanation:
The statement is actually discussing myotubes or skeletal muscle fibers, which are multinucleated, not single-nucleated cells. Unlike cardiac muscle cells and smooth muscle cells, which have a single nucleus, a skeletal muscle cell contains many nuclei due to the fusion of multiple precursor cells called myoblasts during development. This results in muscle fibers that are large and equipped with multiple nuclei, enabling them to produce the vast amounts of proteins needed for muscle contraction and maintenance. The presence of multiple nuclei is what aids in muscle hypertrophy, or the growth and increase of the size of muscle cells. Skeletal muscles undergo hypertrophy in response to exercises like strength training, which necessitates more protein synthesis—a task managed more efficiently by the multiple nuclei.
