The total mass of mitochondria in relation to the mass of cells of various rat organs is: in the pancreas – 7.9%, in the liver – 18.4%, in the heart – 35.8%. Why do the cells of these organs have a different content of mitochondria?
1) Mitochondria are cell energy stations; ATP molecules are synthesized and accumulate in them;
2) for intensive work of the heart muscle, a lot of energy is needed, therefore, the content of mitochondria in its cells is the highest;
3) in the liver, the number of mitochondria compared with the pancreas is higher, since it has a more intense metabolism.
