mitochondria in the cytoplasm

Mitochondria are the energy-producing organelles ofthe cell. Mitochondria have two membrane layers, the outer membrane and the inner membrane. Outer membrane has a smooth surface, while the inner membrane grooved. Dent is called crest. The cells are active or have a high metabolism, such as heart bibs cells, mitochondria contain lots crest.

On the crest there for fosfolirasi oxidative enzymes and the electron transport system. A protein that plays a role in respiration, including the enzyme ATP-makers, made in the inner membrane, the membrane has a large surface so as to boost the productivity of cellular respiration.

Mitochondrial inner membrane divides into two spaces, namely the intermembrane space and mitochondrial matrix.

• Intermembrane space

Intermembrane space is the space between the outer membrane and the inner membrane. Outer membrane can be passed all the small molecules but it can not be passed proteins and large molecules.

• Mitochondrial matrix

Mitochondrial matrix is ​​the space covered by the membrane. Several stages terjadidalam matrix metabolism. The matrix contains enzymes for the Krebs cycle and fatty acid oxidation. The matrix also contains protein DNA, ribosomes, and some types of RNA. Mitochondria can synthesize their own proteins as DNA, RNA, and ribosomes.

Mitochondrial DNA is the code for the proteins and enzymes that work in the inner membrane, whereas the DNA nucleus is the password for matrix proteins and membrane inside.
