Detailed explanation-1: -Mitochondria have a structure distinct from that of other organelles since they contain two membranes: the outer mitochondrial membrane (OMM) and the inner mitochondrial membrane (IMM), which separates the intermembrane space (IMS) from the matrix.
Detailed explanation-2: -The inner membrane forms invaginations, called cristae, that extend deeply into the matrix. The cristae define the third mitochondrial compartment, the crista lumen. The crista membranes contain most, if not all, of the fully assembled complexes of the electron transport chain and the ATP synthase (Fig.
Detailed explanation-3: -Mitochondria are bounded by a double-membrane system, consisting of inner and outer membranes. Folds of the inner membrane (cristae) extend into the matrix.
Detailed explanation-4: -The outer mitochondrial membrane is essentially a double phospholipid membrane that separates the inside of mitochondria from the rest of the cell. This membrane also differentiates the mitochondria from other membrane-bound organelles such as the smooth endoplasmic reticulum.
