Question

Why do heart muscle cells have lots of mitochondria?

Answer 1

Heart muscle cells:

1. The heart muscle has a large number of mitochondria to provide sufficient energy.
2. The heart muscle needs the energy to pump blood into the body.
3. Pumping is promoted by mitochondria.
4. The heart muscle is very active and continuously functioning, so it needs more energy.
5. If the number of mitochondria is low, the heart cannot pump blood.
6. The heart allows the process of contraction and relaxation in the presence of energy.
