Function of Mitochondrial Cristae. Before we can explain the functioning of the crista (plural = cristae), we need to revisit what a mitochondrion does. The mitochondrion is the cellular organelle where cellular respiration takes place.Cellular respiration is the process that creates chemical energy in the form of ATP from simple food molecules.ristae are folds of the inner mitochondrial membrane. The electron transport chain and chemiosmosis takes place on this membrane as part of cellular respiration to create ATP and can be seen in the diagram:
Mitochondrial cristae are folds of the mitochondrial inner membrane that provide an increase in the surface area. This allows a greater space for processes that happen across this membrane. The electron transport chain and chemiosmosis are the processes which help produce ATP in the final steps of cellular respiration.
