What are mitochondria commonly described as in muscle cells?

• A. Energy storage units
• B. Control centers
• C. Power plants of the muscle cell
• D. Waste processing centers

Answer: (C)

The main idea is that mitochondria are the cell’s energy factories, producing the ATP needed for muscle contraction. In muscle cells, the demand for energy is high, so mitochondria carry out cellular respiration to convert nutrients and oxygen into ATP. This energy production is why they’re likened to power plants; they supply the energy that powers muscle fibers during movement. Energy storage terms would point to glycogen or fat stores, which hold energy rather than generate it. Control centers are the nucleus, which governs activities and gene expression, while waste processing centers are lysosomes that break down cellular debris. So describing mitochondria as the power plants of the muscle cell best captures their role.
