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:
1 Swallow-induced peristalsis is called primary peristalsis, and the peristalsis elicited by esophageal distention is called secondary peristalsis. 2  Peristaltic contractions are always preceded by inhibition that, in the case of primary peristalsis, is called deglutitive inhibition.he main function of the esophagus is to propel swallowed food or fluid into the stomach. This occurs through sequential or peristaltic contraction of circular muscle in the esophageal body, in concert with appropriately timed relaxation of the upper and lower esophageal sphincters.
