(Choice A)
An input of energy is not needed for it to occur.

(Choice B)
It allows particles to pass easily between lipids in cell membranes.

(Choice C)
It moves particles from areas of high concentration to areas of low concentration.

(Choice D)
It occurs against the concentration gradient.

ANSWER: CORRECT (SELECTED)
It occurs against the concentration gradient.

According to the research, the correct option is Choice D. Active transport occurs against the concentration gradient.

What is Active transport?

It is a process of exchange of substances through the membrane, that is, it is the movement of substances through the membrane using energy, which implies that it moves through membranes in a direction against its concentration gradient.

The required energy comes from tissue metabolism and is used by the so-called transport pumps (ATPase type) that use the energy released by the hydrolysis of ATP to ADP.

Therefore, we can conclude that according to the research, the correct option is Choice D. Active transport occurs against the concentration gradient.
