Web1 de ago. de 2016 · Cristae can be heterogeneous in their appearance depending on the cell type as well as the developmental and metabolic states of the cell. In contrast, the connection between cristae and inner boundary membrane is formed by a rather homogeneous structure that has been named crista junction. WebIt is the phospholipids that also give rise to other characteristic mitochondrial structures such as cristae (formed from the invaginations of the inner mitochondrial membrane), the matrix (area within cristae) and the intermembrane space (IMS) which separates the outer mitochondrial membrane (OMM) and inner mitochondrial membrane (IMM).
