Question

Why do muscle cells have more mitochondria?

Answer 1

Mitochondria are the energy producing organelles of the cell. The number of mitochondria per cell varies widely depending on the cells energy requirements.

Explanation:

Muscle cells need energy to do mechanical work and respond quickly. Thus a higher number of mitochondria is present so that the cells requirement of energy to perform its specific function is fulfilled.

In humans, erythrocytes do not contain any mitochondria, but heart , kidneys, pancreas and muscle cells contain hundreds or even thousands of mitochondria.
