Some components of it are translocated with the aid of scramblases, flippases, and floppases, resulting in a preponderance of phosphatidyl serine on its (*) inner leaflet.
A replica of this structure is made by evaporating a thin layer of carbon together with a metal in freeze-fracture electron microscopy. According to a recent theory, the inhomogeneity of this structure's composition suggests that it is made up of many micro-domains. Some components of it are translocated with the aid of scramblases, flippases, and floppases, resulting in a preponderance of phosphatidyl serine on its (*) inner leaflet. Integral proteins, such as G-protein coupled receptors, span the width of this structure, which becomes more packed as cholesterol is added. This structure is visualized as a fluid mosaic and it consists of a phospholipid bilayer. For 10 points, name this outer covering of most eukaryotic cells which is further reinforced by a "wall" in plants.
