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.
