Question

"Which molecule would require the use of energy in order to be brought into the cell?

(1)1
(2)2
(3)3
(4)4
"

Answer 1

Answer: 4

Explanation: Molecules move from areas of high concentration to low concertation without the use of energy

Answer 2

The molecule that would require the use of energy in order to be brought into the cell is
(4) 4
Since there are more of these molecules insides the cell than outsides. This means that the process is active transport. The natural direction of molecules is from high to low and going against this would require energy.
