(a) Describe the structure of the plasma/cell membrane. (b) Describe its function. Explain the chemical composition of cellular membranes related to the function of the cell membrane. What is the cell membrane and what is its function?
Membrane Potential: The functional unit of the nervous system is called a nerve cell or neuron. A neuron is composed of a cell body, dendrites, axon, nucleus, and myelin sheath. They conduct nerve impulses by changing the concentration of ions on each side of the plasma membrane. ...

there were further size asymmetries that could also be measured. The homologue pair of the bivalent with the larger major satellite also had consistently the smaller minor satellite and the larger kinetochore Spc24 signal (Fig.1c; Supplementary Fig.1b–d). Therefore, for both bivalents...
The active hemostatic substance in notoginseng is a special non-protein amino acid, dencichine, which has the structure of β-N-oxalyl-l-α,β-diaminopropionic acid [30,31]. Cui et al. [32] also isolated small amounts of flavonoids including quercetin from the roots of notoginseng. Other ...
These are the properties that have most likely determined the evolutionary fate of Archaea and it may be possible for bionanotechnology to adopt these from nature. In this work, we use molecular dynamics simulations to assess at the atomistic level the structure and dynamics of a series of model...
Focal adhesions (FAs) are large, dynamic protein complexes located close to the plasma membrane, which serve as the mechanical linkages and a biochemical signaling hub of cells. The coordinated and dynamic regulation of focal adhesion is required for cell migration. Degradation, or turnover, of FA...
While the sheer versatility of smooth muscle makes it foolish to have a "one model fits all" approach to this subject, we have tried to synthesize ... S Wray,T Burdyga - 《Physiological Reviews》 被引量: 173发表: 2010年 Plasma-membrane Ca2+ pumps: structural diversity as the basis for...
