A main example of active transport is the maintenance of ion gradients across cell membranes, which depends on the function of specific carriers or “ion pumps.” These ion transporters are grouped into three main classes, known as ATPases P, F, and V. The most important will be considered...
The first step of the acid-extruding process is the coupled entry of Na+and X−across the apical membrane, an example of secondary active transport. Because the pK′agoverning the dissociation of monocarboxylic acids (HX ⇋ H++ X−) is generally far below pHi, very little of the ente...

so any fiefdom would be architected by using other patterns as well within its internal implementation. For example, most fiefdoms would use patterns such as data accessors to access the database, service agents to access other services, data transport objects to transport data through the layers...
Work with yeasts has shown that some members of this family are unable to transport sugars; instead, they seem to serve as receptors, influencing gene expression (Özcan et al., 1998; Brown et al., 2006). For example, the S. cerevisiae Snf3p and Rgtp proteins have longer C-terminal ...
For example, when an application has high processing delays, say on the order of 100s of ms or seconds, then we have more flexibility in supporting delay in the network than if the processing delay were on the order of microseconds. An example of interactive bulk applications is large file...
