Biogenesis of mitochondria and chloroplast
WebMitochondria are oval-shaped, double-membrane organelles ( Figure 1) that have their own ribosomes and DNA. Each membrane is a phospholipid bilayer embedded with proteins. The inner layer has folds called cristae, which increase the surface area of the inner membrane. The area surrounded by the folds is called the mitochondrial matrix.

WebDec 19, 2012 · Mitochondria and chloroplasts are both of endosymbiotic origin. In an initial step about 1.5–2.0 billion years ago an α-proteobacterium was taken up into an undisclosed host cell and enslaved to become mitochondrion. Later a mitochondria containing cell took up an ancestral photosynthetic cyanobacterium, which became a … WebChloroplasts and mitochondria originated as bacterial symbionts. The larger, host cells acquired genetic information from their prokaryotic guests by lateral gene transfer. The …
WebThe present volume focuses on the biogenesis of three related membranes.
