IB Biology HL B2.1.6 Channel proteins
Practise explaining facilitated diffusion through channel proteins, including gradients, passive movement, polar solutes and rate graphs.
How this is tested
- explain why polar molecules such as glucose use hydrophilic protein channels
- apply concentration gradients to passive movement without ATP use
- interpret facilitated diffusion graphs showing channel saturation at high concentration
