Quizplus · Accepted Answer

Low myoglobin content would not be exhibited in the muscle cells of a marathon runner's legs because myoglobin is responsible for binding oxygen in the muscle cells and providing energy for aerobic respiration. Marathon runners require a lot of oxygen to sustain their endurance activities, and hence, they have a higher concentration of myoglobin in their muscle cells. Therefore, the correct answer is B because low myoglobin content in the muscle cells would not benefit a marathon runner.
