– semi-autonomous organoids characteristic of eukarnot cells. Mitochondria occupy a significant part of the cytoplasm. They have an elongated, elongated shape, and their size ranges from 1.5 to 10 microns. Mitochondria have a rather complex structure. Their outer membrane is smooth, and the inner has folds and outgrowths – crista significantly increase the inner membrane surface.
Respiratory enzymes are located on the inner membrane, providing the process of oxidative phosphorylation, as a result of which ATP molecules are synthesized. Mitochondria are the “energy stations” of a cell. In the process of breathing in them, the final oxidation of substances by atmospheric oxygen occurs.
The presence of DNA, RNA, and ribosomes in the mitochondria ensures the synthesis of their own mitochondrial proteins, the transmission of hereditary information in the process of division.
Remember: The process of learning a person lasts a lifetime. The value of the same knowledge for different people may be different, it is determined by their individual characteristics and needs. Therefore, knowledge is always needed at any age and position.
