The rate of carrier-mediated transport is limited by which one of the following
A)protein location in the membrane
B)osmolarity
C)tonicity
D)competition with other molecules

Question

Quizplus · Accepted Answer

Carrier-mediated transport involves the use of specific carrier proteins to transport molecules or ions across the membrane. The rate of this transport is limited by the availability of carrier proteins and their competition with other molecules for binding sites. Therefore, option D, competition with other molecules, is the best choice.
