WebAug 1, 2011 · During 1990s, there seemed to be a convincing argument to explain the origin of eukaryotes and their mitochondria: The protoeukaryote must have evolved from an archaebacterial ancestor, because most eukaryotic informational genes (i.e., those involved in the genetic machinery) are of archaebacterial origin ( Rivera et al. 1998 ). WebJul 30, 2024 · Mitochondria are membrane-bound organelles enclosed by a double membrane. They have a smooth outer membrane enclosing the organelle and a folded inner membrane. The folds of the inner membrane are called cristae, the singular of which is crista, and the folds are where the reactions creating mitochondrial energy take place.
