Are Cristae the Same Thing as Inner Membrane?

The outer membrane surrounds the mitochondria. It is a semi-permeable membrane similar to the cell membrane. The inner membrane is impermeable. ... The folds created by the inner membrane are known as the cristae, which contain proteins and molecules that participate in cellular respiration.

Is inner membrane and cristae same?

The inner membrane forms invaginations, called cristae, that extend deeply into the matrix. The cristae define the third mitochondrial compartment, the crista lumen.

Is the inner mitochondrial membrane The cristae?

Mitochondrial Membranes, Structural Organization

The inner membrane is contained by the smaller outer membrane because the inner membrane is invaginated or involuted. The internal compartments defined by the infoldings of the inner membrane are called 'cristae' and the space they enclose is the intracristal space.
