Question

2. Which of the following correctly identifies active transport? (1 point)

Transport proteins move large molecules from areas of low concentration to areas of high concentration using cellular
energy
Transport proteins move large molecules from areas of low concentration to areas of high concentration without the use of
cellular energy
Small molecules move from areas of high concentration to areas of low concentration using cellular energy to enter a cell.
Small molecules move from areas of low concentration to areas of high concentration without using cellular energy to enter a
cell.

Answer 1

Answer: D
