General Information
Term mitochondrial matrix ID (Ontology) GO:0005759 (Gene Ontology)
Definition The gel-like material, with considerable fine structure, that lies in the matrix space, or lumen, of a mitochondrion. It contains the enzymes of the tricarboxylic acid cycle and, in some organisms, the enzymes concerned with fatty acid oxidation.[ ISBN:0198506732 ]
Also Known As "mitochondrial lumen"
