Q

state three functions of membrane protein

A

1.they function as receptors for transmitter
2.protein molecules have pores for the movement of water soluble substances across the cell membrane
3.carrier proteins transport large metabolic substances like glucose

glucose cannot easily go accross the membrane so it requires active transport
