The infoldings of the inner membrane of mitochondria is referred to as ______.
Cristae
The mitochondrion is a double membrane-bound organelle - an outer membrane and an inner membrane. 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 such as ATP synthesis. The outer membrane acts as a selectively permeable membrane which is the gateway to the mitochondria.
