Special features of mitochondrial matrix?
Answers
The mitochondrion consists of an outer membrane, an inner membrane, and a gel-like material called the matrix. This matrix is more viscous than the cell's cytoplasm as it contains less water. The mitochondrial matrix has several functions.
It is where the citric acid cycle takes place. This is an important step in cellular respiration, which produces energy molecules called ATP. It contains the mitochondrial DNA in a structure called a nucleoid. A mitochondrion contains its own DNA and reproduces on its own schedule, apart from the host cell's cell cycle. It contains ribosomes that produce proteins used by the mitochondrion. It contains granules of ions that appear to be involved in the ionic balance of the mitochondrion.
This picture shows the mitochondrion. Folds of the inner membrane are called cristae and this is where the matrix resides.
Features of mitochondrial matrix are as follows-
1. Matrix is found in the inner aqueous compartment of the mitochondria.
2. This Matrix have enzyme for kreb cycle.
3. 70s ribosomes RNA are found in this matrix.
4. Single double stranded circular naked DNA is found in it.
5.They are also called semi-autonomous cell organelle due to presence of DNA and RNA both.
6. Also called powerhouse of the cell because energy is formed in the matrix of mitochondria in the form of ATP.
7. They compute the process of protein synthesis as well.
8. Also known as Storage batteries because they also store energy.
9. Overall this is the most busy or active organelle in the cell.
