国际学校生物老师解读IB生物,感兴趣的同学记得收藏哦~ IB生物分为SL(standard level)和HL(higher level) SL有6个topic∶细胞生物,分子生物,遗传学,生态学,物种进化以及多样性和人体生理。 HL除了上述6个topic外还要加上∶核酸,新陈代谢,细胞的呼吸与光合作用,植物生理,遗传与进化和动物生理。 Optional To
1. Membrane activity is a critical factor in the biology of small molecules 2. Lipid mediated essential functions of gases in membrane proteins 3. General anesthetics: utilizing the membrane as a conduit to modulation sites in ion channels 4. Interactions of steroid hormones with lipid bilayers an...
plasma membrane- a thin membrane (a double layer of lipids) enclosing the cytoplasm of a cell; proteins in the membrane control passage of ions (like sodium or potassium or calcium) in and out of the cell; "all cells have a cell membrane" ...
After the maturation process, the VZV progeny virion bud at the plasma membrane but remain associated at the cell surface, a phenomenon that is quite unique among all herpesviruses7. Because the viral fusogenic glycoproteins are expressed on both the viral envelope and the membrane of infected ...
We found that the plasma membrane proteins form multi-protein assemblies that are long lived (minutes), and in which protein diffusion is restricted. The formation of the assemblies is dependent on cholesterol. They are separated and anchored by the actin cytoskeleton. Specific proteins are ...

To account for this delay, it has been suggested that secondary fusion requires the recruitment of components of the fusion machinery from the plasma membrane (4). This might, for example, involve the migration of syntaxin 2 into the membrane of the fused granule, although this would raise ...
Plasma membrane (PM) H+-ATPases are the primary pumps responsible for the establishment of cellular membrane potential in plants. In addition to regulating basic aspects of plant cell function, these enzymes contribute to signaling events in response to diverse environmental stimuli. Here, we focus...
Maintaining a Balance. 1.The plasma membrane is a SELECTIVELY (SEMI-) PERMEABLE membrane that allows nutrients and wastes to enter and exit the cell. The Plasma Membrane - Gateway to the Cell Organelles that work together in the business of life and Cellular boundaries. ...
Total internal reflection fluorescence (TIRF) microscopy offers powerful means to uncover the functional organization of proteins in the plasma membrane with very high spatial and temporal resolution. Traditional TIRF illumination, however, shows a Gauss
