Answer;
-Mitochondria
Explanation;
-Mitochondria are organelles, or parts of a eukaryote cell. They are in the cytoplasm, not the nucleus. They make most of the cell's supply of adenosine triphosphate (ATP), a molecule that cells use as a source of energy.
-Heart muscle cells have the most abundant mitochondria,with about 5,000 mitochondria per cell – that contain far more mitochondria than any other organ in body. This is because they are constantly-beating, heart works harder than any other organ in the body.
-Heart muscle cells have extra-special demand for ATP to keep the heart pumping 24/7 over a lifetime. By comparison, the tissue of the biceps muscle has about 200 mitochondria per cell.
