Detailed explanation-1: -The inner membrane of the mitochondrion folds inwards, forming the cristae. This folding allows a greater amount of membrane to be packed into the mitochondrion. The data in this study demonstrate that subunits e and g of the mitochondrial ATP synthase are involved in generating mitochondrial cristae morphology.

Detailed explanation-2: -These folds are called ‘cristae’.

Detailed explanation-3: -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.
