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

Detailed explanation-3: -Cristae are folds in the inner mitochondrial membrane. Mitochondria are organelles in eukaryotic cells. The major function of cristae is to increase the surface area of the mitochondrial membrane. This allows membrane processes to produce more energy at a faster rate.

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.

Detailed explanation-5: -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).
