Detailed explanation-1: -Mitochondrion possesses double membrane as its covering. The outer smooth surface and the inner membrane forms infoldings called as cristae, which increases surface area for more formation of energy in the form of ATP.

Detailed explanation-2: -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.

Detailed explanation-3: -The inner membrane of the mitochondrion folds inwards, forming the cristae.

Detailed explanation-4: -The inner membrane (IM) has many folds, termed cristae, which increase the surface area available for mitochondrial respiration and are the site of electron transport and oxidative phosphorylation (OXPHOS).

Detailed explanation-5: -Cristae are multiple tubular or lamellar invaginations into the matrix separated from the rest of the IMM by cristae junctions (CJs). The CJs act as diffusion barriers and therefore contribute to delimiting cristae-bounded biochemical processes [14]. Structure of mitochondrial microcompartments.
