• Describe how solutes cross cell membranes • Explain how charge, size, and solubility affect solute movement across cell membranes • Contrast how transporters, pumps & channels work • Describe how ion channels are gated • Describe how epithelial transport works

1. Large four protein complexes Ⅰ,Ⅱ,Ⅲ and Ⅳ embedded in the inner mitochondrial membrane. 2. Electron transport via the respiratory chain. 3. ATP synthesis by oxidative phosphorylation. 4. common poisons that block electron transport and oxidative phosphorylation. 5. Substrates shuttle into mitochondial respiratory chain

1.1 What are transport systems 1.2 What is traffic control system 1.3 What are the differences between transport planning and traffic control 1.4 History of the traffic control system 1.5 Next generation of traffic control system

The general approach Earlier Parts have given a broad picture of the economic environment within which marine transport operates, and the mechanics of making economic calculations. Ship design links the two, i.e., the marine transport requirements must be developed into a series of feasible ship designs

一、被动运输被动运输( passive transport)是指通过简单扩散或协助 (outside) lipid-soluble molecules,扩散实现物质由高 O2, CO2, H2O浓度到低浓度方向的跨膜转运。(一)简单扩散 (inside)

THE CELL WALL Before traversing the plasma membrane(p. m., ions must first cross the cell wall and contact the p. m the bulk flow of soil solution coul theoretically carry inorganic ions into the cell wall and through the apoplastic pathway. The thickness of a cell wall is in the range of 500 to 1000 nm. It is porous
