1.	The channel in a membrane protein by which an ion or molecule can be transported in and out of the cell membrane is known as ___________(a) Permeation pathway(b) Permeate channel(c) Permeation channel(d) Channel pathwayI had been asked this question during an interview.This key question is from Cellular Membranes in portion Cellular Membranes of Cell Biology
Answer» The correct answer is (a) PERMEATION pathway To explain I would say: Transmembrane PROTEINS act as CHANNELS from the intracellular and extracellular transport of ions and molecules. The CHANNEL through which the transport is done is called permeation pathway as it helps in the permeation of solutes and ions through the membrane.
