Correct Answer

Explanation

Mitochondria are known as the powerhouse of the cell, as they are responsible for producing ATP, which is the primary energy source for cells. The red fibres of muscle contain a high concentration of mitochondria, which allow for the production of ATP to power muscle contraction. In addition to mitochondria, red fibres also contain a high concentration of myoglobin, a red-colored protein that stores oxygen and allows for sustained aerobic respiration in the muscle.
