6
Q
Bacterial Potassium channel
A
kcsA
7
Q
What is relative permeability?
A
How easily ions can move across
8
Q
What happens if Phenylanine is added with sodium coupled co transporter?
A
It is transported into cell via sodium amino co transport so depolarises then recovers because potassium channels open
