Explanation:
Heart muscle cells cannot rely on fermentation for long period of time because heart muscles have long refractory period which does not allow it to use the fermentation process. They have rich blood supply and have capillary density 4 times more than normal skeletal muscles. The anaerobic capacity is limited in the heart which does not allow the heart muscle cells to use fermentation process for metabolism. Our heart requires oxygen in large amount and very quickly for ATP production.
