Detailed explanation-1: -In the mitochondrion, the matrix is the space within the inner membrane. The word “matrix” stems from the fact that this space is viscous, compared to the relatively aqueous cytoplasm.

Detailed explanation-2: -The intermembrane space (IMS) is the space occurring between or involving two or more membranes. In cell biology, it is most commonly described as the region between the inner membrane and the outer membrane of a mitochondrion or a chloroplast.

Detailed explanation-3: -’The powerhouse of the cell’ has an outer and an inner membrane separating two aqueous sub-compartments, the matrix and intermembrane space (IMS).

Detailed explanation-4: -Abstract. Mitochondria contain two aqueous subcompartments, the matrix and the intermembrane space (IMS). The matrix is enclosed by both the inner and outer mitochondrial membranes, whilst the IMS is sandwiched between the two.
