Question

Which type of cell has the greatest number of mitochondria? A. skin cell B. muscle cell C. blood cell D. fat cell

Answer 1

B. Muscle cell, also known as myocytes, have more abundant mitochondria than the other cells listed. This is primarily due to the fact that sustained muscular contractions require massive amounts of cellular energy, transported throughout the cell within the phosphate bonds of Adenosine Tri-Phosphate (ATP) molecules. Mitochondria are the cells' organelles that produce ATP, giving them the nickname "energy powerhouses of the cell."
