Function of channel and carrier proteins
WebChannel proteins are transport proteins that have a hydrophilic channel that certain molecules or ions can use as a tunnel through the membrane (Ex: aquaporins for water). … WebThese channel and carrier proteins mainly transport molecules passively. Active transport, on the other hand, needs energy. Why does active transport require energy? a) It transports molecules against an electrochemical gradient b) The transporters need to open wider because it transports bigger molecules c) It is faster than passive transport
