In carrier kinetics, saturation means that
A) All of the carriers are busy and transport is limited by the number of carriers
B) No more transport is possible
C) Equilibrium has been reached
D) The membrane can hold no more solute
E) There are no free C=C double bonds

Saturation in carrier kinetics occurs when all carriers are occupied, meaning transport across the membrane is at its maximum and limited by the number of carriers available. This does not imply no more transport is possible or that the membrane is physically full; it simply means the rate of transport cannot increase further with an increase in solute concentration because all carrier proteins are already in use.
