a) Nonmediated transport b) Mediated transport c) Nonmediated transport d) Mediated transport
Work Step by Step
a) Ethanol is a non-polar compound and therefore passes through the membrane by non-mediated transport. b) As glycine is a polar molecule, it is transported through mediated transport. c) Cholesterol is a steroid and is therefore transported through non mediated transport. d) ATP requires a driving force to pass through a membrane and must therefore be transported by mediated transport.
