Describe the structural and functional differences between RER and SER.
Phospholipids are among the principal membrane components. Describe the arrangement of a phospholipid molecule.
A Golgi body and Golgi vesicles cannot be seen in Fig. 1.1. Describe the characteristics, apart from the presence of Golgi vesicles, that would allow you to recognise a Golgi body in a transmission electron micrograph of another part of the same liver cell.
Some Golgi vesicles carry secretory proteins for export from the cell. Describe the sequence of events from packaging a secretory protein into a Golgi vesicle until its release from the cell.
Some Golgi vesicles contain glycoproteins or glycolipids that are added to the cell surface membrane. Outline the function of glycolipids in the cell surface membrane.
