Matrix
The space/ supporting medium within which something is formed. Can be either Intracellular or Extracellular.
An example of an intracellular matrix is the large internal compartment of a Mitochondria or the internal compartment of Chloroplasts (stroma). In the mitocondrial matrix, an important process citric acid cycle takes place, - this is cruicial for cellular respiration that produce ATP (energy molecules)
The extracellular matrix is the composite of secreted Proteins and Polysaccharides, in which cells are embedded [1].
