Question

You observe a small, nonpolar molecule near a membrane. how would this molecule likely transport across the membrane? you observe a small, nonpolar molecule near a membrane. how would this molecule likely transport across the membrane? carrier-mediated facilitated diffusion simple diffusion active transport channel-mediated facilitated diffusion

Answer 1

It will transported across plasma membrane by simple diffusion. simple diffusion refers to a process by which molecules will pass across plasma membrane without the aid of channels located on the surface of the membrane. since the molecule identified was polar once it enter in hydrophobic region of the membrane it will not stick since this region is non-polar and therefore it will move easily across that region. 

Answer 2

The answer is simple diffusion Simple diffusion is a process in which the substance passes through the membrane without the help of any external agent or intermediary the force that drives the molecules is diffusion.Diffusion in biology is movement of molecule from a region of high concentration level to region of low concentration level.
