Quizplus · Accepted Answer

Fast-twitch cells are muscle cells that contract rapidly, are rich in glycogen deposits, and depend on anaerobic respiration to produce ATP. Slow-twitch cells, on the other hand, contract more slowly, have lower glycogen stores, and rely more on aerobic respiration. Myoglobin and hemoglobin are proteins involved in transporting oxygen, and are not cell types.
