Which type of cells would you expect to have the most mitochondria?

• A. Red blood cells
• B. Muscle cells
• C. Skin cells
• D. Nerve cells

Answer: (B)

Verified step by step guidance

1. Understand the function of mitochondria: Mitochondria are known as the powerhouses of the cell because they produce ATP, the energy currency of the cell, through cellular respiration.
2. Consider the energy requirements of different cell types: Cells that require more energy will have more mitochondria to meet their energy demands.
3. Analyze the energy needs of each cell type: Muscle cells are highly active and require a lot of energy for contraction and movement, thus they have a high number of mitochondria.
4. Compare with other cell types: Red blood cells do not have mitochondria as they rely on anaerobic respiration. Skin cells have lower energy demands compared to muscle cells. Nerve cells have mitochondria but not as many as muscle cells due to their different energy requirements.
5. Conclude that muscle cells have the most mitochondria due to their high energy needs for sustained and intense activity.
