Structure of the Plasma Membrane The phospholipid bilayer The plasma membrane is composed of phospholipid bilayer – two layers of phospholipids are arranged to allow the membrane to exist in a watery environment. The phospholipid bilayer has polar heads facing outside and nonpolar tails facing inside...
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" ...
The Cell Membrane The “cell membrane” is also known as “the plasma membrane.” To survive, ALL living things must maintain a balance regardless of internal and external conditions. http://www.nature.com/scitable/content/ne0000/ne0000/ne0000/ne0000/14704938/SelectiveTransport_ksm_2_1.jpg T...

This chapter discusses the importance of plasma membrane proteins in carrying out numerous cellular functions at the interface between the internal and external environments. The plasma membrane is actively involved in the uptake by endocytosis of a variety of materials from the surrounding medium. The...

The EAAT2b-unique PDZ-binding domain provides a mechanism by which EAAT2b trafficking to the plasma membrane is modulated. Unlike EAAT2a, which is constitutively cycled to the membrane, Underhill et al. (2015) have shown that stable EAAT2b localization at the cell surface is achieved by its...
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 Topics包括∶神经与行为学,生物科技与生物信息学,生态保护和人体生理。 SL和HL都要从optional topics里选一个topic,但...
However, a series of challenges remains to be addressed before mRNA can be established as a general therapeutic modality with broad relevance to both rare and common diseases. An array of new technologies is being developed to surmount these challenges, including approaches to optimize mRNA cargos,...
