Detailed explanation-1: -Mitochondrial cristae are folds of the inner membrane that increase the surface area. This provides larger space for processes that happen across the membrane, like ATP synthesis.

Detailed explanation-2: -The inner membrane of the mitochondrion folds inwards, forming the cristae.

Detailed explanation-3: -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-4: -Mitochondrial cristae are the folds within the inner mitochondrial membrane. These folds allow for increased surface area in which chemical reactions, such as the redox reactions, can take place.
