Friday 14 October 2016
Membrane transport. (Optional advanced topics)
Reading: VVP4e - Ch.10, pp.288-312.
Summary
Thermodynamics of transport
The transmembrane difference in chemical potential determines the spontaneous direction movement.
Passive-mediated transport
Ionophores: Facilitated diffusion; transmembrane protein channels.
Active transport
Coupling vectorial transport to ATP hydrolysis. The (Na+-K+)-ATPase and Ca2+)-ATPase. ABC transporters. Secondary active transport.
