Real-Time Transport Protocol Real-time traffic v.S. multimedia traffic Real-time communication is the almost simultaneous production and use of the data, ignoring the short delay in transmission

1. electron transport-an overview 在生物氧化过程中,代谢物脱下的氢经过一系 列的传递体的传递,最终交给分子氧生成水,这一 电子传递体系称为呼吸链。 在生物细胞中,接受代谢物上脱下的氢(或电 子)的载体有三种nAD、NADP和FAD

The short distance transports of nutrients There are two main steps nutrients translocation in plant after nutrients absorbed by the root. One is the centripetal transport from the rhizoplane through the cortex tissue of the roots towards the xylem vessels of the central cylinder. Another one is the vertical transport from from the root towards the leaves

25.1 Introduction 25.2 Oligosaccharides are added to proteins in the ER and Golgi 25.3 The Golgi stacks are polarized 25.4 Coated vesicles transport both exported and imported proteins 25.5 Different types of coated vesicles exist in each pathway 25.6 Cisternal progression occurs more slowly than vesicle movement 25.7 Vesicles can bud and fuse with membranes 25.8 SNAREs control targeting 25.9 The synapse is a model system for exocytosis 25.10 Protein localization depends on specific signals 25.11 ER proteins are retrieved from the Golgi 25.12 Brefeldin A reveals retrograde transport 25.13 Receptors recycle via endocytosis 25.14 Internalization signals are short and contain tyrosine
