Mitochondrial Matrix

Mitochondria are intraeukaryotic organelles that play an important role in cellular energy metabolism. One of the most mysterious functions of mitochondria is their matrix—the ultrastructural structure of mitochondria that surrounds the inner surfaces of membrane vesicles and performs numerous functions in biological processes.

Mitochondrial matrices are complex molecular systems consisting of proteins, nucleic acids, lipids, carbohydrates and many other components. These structures play a key role in regulating mitochondrial activity, as well as in controlling metabolic processes in the cell.

Structure of the mitochondrial matrix

The mitochondrial matrix consists of three different structures: nuclear, ribosomal and membrane matrices. The nuclear matrix forms the center of the mitochondrial membrane. It includes many unique proteins and lipids that regulate many metabolic processes in cells. One of the key components of the nuclear matrix is ​​mtDNA, or mitochondrial DNA.
