BIO-1 Lecture Notes - Lecture 10: Light-Independent Reactions, Intermembrane Space, Atp Synthase
Document Summary
Assumes that mitochondria and chloroplasts are evolutionarily derived from free-living. With time these symbionts have been integrated into the host cells. Consists of inner and outer membrane and 2 compartments: the matrix and intermembrane. Outer membrane separates the mitochondrion from cytosol. Inner membrane is site of etcs and atp synthase. Flat cristae occurs in plants, animals and fungi. Tubular cristae occurs in brown algae and in many protist groups. It is the cytoplasm of the mitochondrion and. Intermembrane space lies between inner and outer mitochondrial membranes; it is the. Have 3 membrane systems: outer, inner, and thylakoid. 3 compartments: stroma, thylakoid spaces and inter membrane space. Outer membrane separates the chloroplast from the cytosol compartment. Inner membrane surrounds the stroma of the chloroplast. Thylakoid membranes are flattened sacs that lie within the stroma of the chloroplast. Stroma is the cytoplasm of the chloroplast and lies within the inner membrane.
