Bevat de belangrijkste begrippen rond cel biologie en cel anatomie uit het boek Essential Cell Biology met uitleg
This summary is based on the 3rd edition of Essential Cell Biology from Alberts et al. The remaining chapters can be accessed when logged in and can be found here: Second part of the summary Cells are the fundamental units of life; all living things are made of cells. The present-day cells are believed to have evolved from an ancestral cell that excited more than 3 billion years age. Cells vary enormous in appearance and function, however all living cells have a similar basic chemistry.With the invention of the microscope, it became clear that plants and animals are assemblies of cells, that cells can also exist as independent organisms, and that cells individually are living in the sense that they can grow, reproduce, convert energy from one form into another, respond to their environment, and so on. Although cells are varied when viewed from the outside, all living things are fundamentally similar inside. And in all living things, genetic instructions, called genes, are stored in DNA molecules. In every cell, the instructions in the DNA are read out, or transcribed, into a chemically related set of molecules made of RNA. The messages carried by the RNA molecules are in turn translated into yet another chemical form: they are used to direct the synthesis of a huge variety of large protein molecules that dominate the behaviour of the cell....
This summary is based on the 3rd edition of Essential Cell Biology from Alberts et al. The first 10 chapters are open access and can be found here: First part of the summary Cell membranes enable a cell to create barriers that confine particular molecules to specific compartments. The simplest bacteria have only a single membrane, the plasma membrane. Eucaryotic cells, however, contain in addition a profusion of internal membranes that enclose intracellular compartments. All cell membranes are composed of lipids and proteins and share a common general structure. The lipid component consists of many millions of lipid molecules forming a lipid bilayer. This lipid bilayer gives the membrane its basic structure and serves as a permeability barrier. The lipids in cell membranes combine two very different properties in a single molecule: each lipid has a hydrophilic (‘water-loving’) has and one or two hydrophobic (‘water-hating’) hydrocarbon tails. There are three major classes of membrane lipid molecules:PhospholipidsSterolsGlycolipidsThe most abundant lipids in cell membranes are phospholipids, and the most common type of phosphoslipid in most cell membranes is phosphatidylcholine. Molecules with both hydrophilic and hydrophobic properties are termed amphipathic. This chemical property plays a crucial part in driving...
