#4.2i
Know the structure of the cell surface membrane with reference to the fluid mosaic model.
#4.2ii
Understand how passive transport is brought about by:
- diffusion
- facilitated diffusion (through carrier proteins and protein channels)
- osmosis.
#4.2iii
Understand how the properties of molecules affects how they are transported, including solubility, size and charge.
#4.2iv
Know that large molecules can be transported into and out of cells through the formation of vesicles, in the processes of endocytosis and exocytosis.
#4.2v
Understand the process of active transport, including the role of ATP.
#4.2vi
Know that phosphorylation of ADP requires energy and that hydrolysis of ATP provides an accessible supply of energy for biological processes.
