Question

which of the following provides the best description of active transport of materials across the cell membrane?
○ active transport requires energy and moves materials from areas of relatively higher to lower concentration.
○ active transport requires energy and moves materials from areas of relatively lower to higher concentration.
○ active transport does not require energy and moves materials from areas of relatively lower to higher concentration.
○ active transport does not require energy and moves materials from areas of relatively higher to lower concentration.

Explanation:

Active transport is a process that uses energy (usually ATP) to move substances against their concentration gradient, from an area of lower concentration to an area of higher concentration.

Answer:

Active transport requires energy and moves materials from areas of relatively lower to higher concentration.
