Biology - Cell membrane


biology - Cell membrane

of evolution, a eukaryotic cell engulfed these 2 types of bacteria, leading to the formation of mitochondria and chloroplasts inside eukaryotic cells. Lipid vesicles and liposomes are formed by first suspending a lipid in an aqueous solution then agitating the mixture through sonication, resulting in a vesicle. The cell membrane may also envelope something on the outside and surround it, taking it into the cell. Approximately 75-85 of the cell s volume is due to water making it an indispensable solvent as a result of its polarity and structure. Fatty acids may be saturated or unsaturated, with the configuration of the double bonds nearly always "cis". In plants, which lack cholesterol, related compounds called sterols perform the same function as cholesterol. 7 In 1895, Ernest Overton proposed that cell membranes were made of lipids. This forms a continuous, spherical lipid bilayer. The outer membrane of the gram-negative bacteria differ from other prokaryotes due to phospholipids forming the exterior of the bilayer, and lipoproteins and phospholipids forming the interior.

Cell biology (also called cytology, from the Greek, kytos, vessel ) is a branch of biology that studies the structure and function of the cell, the basic unit of life.

Alberts, Bruce; Johnson, Alexander; Lewis, Julian; Raff, Martin; Roberts, Keith; Walter, Peter (2002). Tight junctions join epithelial cells near their apical surface battles in World War I to prevent the migration of proteins from the basolateral membrane to the apical membrane. To name a few. The cell shape varies among the different types of organisms, and are thus then classified into two categories: eukaryotes and prokaryotes. The main constituents of the general molecular composition of the cell includes: proteins and lipids which are either free flowing or membrane bound, along with different internal compartments known as organelles.
