Transporters that move two substances at once are known as
A) uniporters.
B) facilitated transporters.
C) secondary active transporters.
D) coupled transporters.
E) directional transporters.

Question

Quizplus · Accepted Answer

Coupled transporters move two substances at once, often using the energy from one substance moving down its concentration gradient to power the movement of the second substance against its concentration gradient. Uniporters move only one substance, facilitated transporters move one substance down its concentration gradient with the help of a carrier protein, secondary active transporters use the energy from one substance moving down its gradient to power the movement of a second substance against its gradient, and directional transporters are not a recognized category.
