中文简介:
即使是最简单的生物体也能在其不断变化的环境中检测和响应事件。类似地,在多细胞生物体内,细胞被细胞外环境包围,信号从中接收和响应。细胞外事件通过涉及许多细胞内分子的一系列激活/失活步骤被解码并传输到单个细胞的相关部分。这种沿分子途径传递的信息称为信号转导;有时也称为“信号”。 本章所示的分子模型是使用图例中所示的布鲁克黑文蛋白质数据库(pdb)文件生成的。可以使用合适的分子查看程序(如Viewerlite tm)下载、查看和操作这些文件。 这门开放学习课程提供了一个科学3级学习的范例。
课程简介: Even the simplest organisms can detect and respond to events in their ever-changing environment. Similarly, within a multicellular organism, cells are surrounded by an extracellular environment from which signals are received and responded to. Extracellular events are decoded and transmitted to relevant parts of individual cells by way of a series of activation/deactivation steps involving many intracellular molecules. This relay of information along molecular pathways is called signal transduction; it is sometimes also simply referred to as ‘signalling’. The molecular models shown in this chapter were produced using the Brookhaven protein data base (pdb) files indicated in the figure legends. These files can be downloaded, viewed and manipulated using a suitable molecular viewing programme, such as Viewerlite tm. This OpenLearn course provides a sample of Level 3 study in Science.
