Organelles and Transport Regents Review

Muscle cells in athletes often have more mitochondria than muscle cells in nonathletes. Based on this observation, it can be inferred that the muscle cells in athletes

• have a smaller demand for cell proteins than the muscle cells of nonathletes

• reproduce less frequently than the muscle cells of nonathletes

• have nuclei containing more DNA than nuclei in the muscle cells of nonathletes

• have a greater demand for energy than the muscle cells of nonathletes
