All the cells require energy in order to work, however, the cells of the muscles possess an unusually greater need for energy. The muscles go through vigorous activity and such amount of energy provided by the organelles known as mitochondria.
These known as the powerhouse of the cells, transform glucose into ATP that is a molecule, which can accumulate huge concentrations of easily accessible energy. The muscle cells comprise a huge amount of mitochondria in comparison to any other kind of cell so that they can forcefully and briskly react towards the continuous body requirement for different kinds of movement.
our body tells us we need more energy by feeling hungry (like your stomach is rumbling), and it also tells us by feeling tired. also if your body is short on fluids, you will start feeling fatigued.
