Question

question 1-1
essential nutrients move through a cell membrane by both passive transport and active transport. which of the following correctly describes the transport of materials across a
cell membrane?
○ active transport requires chemical energy to move nutrients from areas of low concentration to areas of high concentration.
○ passive transport requires chemical energy to move nutrients from areas of low concentration to areas of high concentration.
○ active transport moves nutrients from areas of high concentration to areas of low concentration without the use of chemical energy.
○ passive transport moves nutrients from areas of low concentration to areas of high concentration without the use of chemical energy.

Explanation:

Active transport is a process that requires chemical energy (usually in the form of ATP) to move nutrients from areas of low concentration to areas of high concentration against the concentration gradient. Passive transport, on the other hand, does not require chemical energy and moves substances along the concentration gradient (from high to low concentration).

Answer:

Active transport requires chemical energy to move nutrients from areas of low concentration to areas of high concentration.
