SSC MTS EXAM

Detailed explanation-1: -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-2: -The inner membrane is contained by the smaller outer membrane because it is invaginated or involuted. The internal compartments defined by the infoldings of the inner membrane are called cristae and the space they enclose is the intracristal space.

Detailed explanation-3: -A crista (/ˈkrɪstə/; plural cristae) is a fold in the inner membrane of a mitochondrion. The name is from the Latin for crest or plume, and it gives the inner membrane its characteristic wrinkled shape, providing a large amount of surface area for chemical reactions to occur on.
