mitochondrial matrix
Powerhouse's inner space
The mitochondrial matrix is the innermost compartment of a mitochondrion, enclosed by the inner membrane.
This dense fluid contains enzymes for the citric acid cycle, mitochondrial DNA, and ribosomes.
Most of the cell's ATP production occurs here through oxidative metabolism: The mitochondrial matrix is where pyruvate gets broken down.
