Question

what are prions what role do they play in diffusion

Answer 1

here's your answer



=>porins and their role is diffusion they are proteins and hydrophilic channels which form huge pores
=>in outer membranes of plastics mitochondria as well as certain bacteria following molecules up to size of small
=>proteins to pass through some are small and specific
example voltage gated potassium channel is plasma membrane of neurones
=>permits k plus to diffuse into cytosol as part of sequence of electrical event or nerve impulse channels open and close according to voltage across the membrane
the aquaporins are water channels to diffusicta of water
