A transport system that moves one solute into the cell and another one out of the cell during a single cycle accompanied by the expenditure of energy through ATP hydrolysis could be called _______
A)an active antiport
B)an active uniport

D)an active symport
E)a passive symport

Question

Quizplus · Accepted Answer

This transport system is described as moving solutes in opposite directions (one in and one out of the cell) and requiring the expenditure of energy through ATP hydrolysis, which is characteristic of active transport. "Antiport" refers to the movement of solutes in opposite directions, and "symport" refers to the movement of solutes in the same direction. Therefore, the best choice is A, active antiport.
