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" ...
These size-dependent density gradients are consistent with a process of lateral diffusion of membrane components that are inserted proximally into the plasma membrane. The membrane composition of the growth cone, however, appears to be independent of these diffusion gradients; it displays a mosaic ...
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...
Structure of the Plasma Membrane Other components of the plasma membrane The fluid mosaic model describes the phospholipids in the bilayer as a “sea” in which other components can float and move around. The different substances in the plasma membrane create a pattern or mosaic on the surface ...
The gas permeable membrane is one of the main components of the ECMO unit, which is a barrier between blood and sweep gas. Silicone rubber has good oxygen permeability and blood compatibility, but its function of discharging carbon dioxide is poor. Nowadays, polymeric hollow fiber membranes are ...
It appears, therefore, that not only the plasma membrane but also the cell wall greatly influences the freezing behavior of plant cells. 展开 关键词: Cell wall Chilling injury Cold acclimation Intracellular freezing Saintpaulia Vigna DOI: 10.1007/s00425-002-0814-5 被引量: 115 ...
1. 1. The plasma membrane potential and the mitochondrial membrane potential of P. yoelli was examined by fluorescence microscopy using rhodamine 123 and by transmembrane distribution of tetraphenylphosphonium. 2. 2. The mitochondrion of P. yoelii, free of gametocyte stage, maintained a high negat...
Mechanoelectrical transduction channels of hair cells allow for the entry of appreciable amounts of Ca(2+), which regulates adaptation and triggers the mechanical activity of hair bundles. Most Ca(2+) that enters transduction channels is extruded by the plasma membrane Ca(2+)-ATPase (PMCA), ...
