Question

Apply Small lipid molecules are in high concentration outside a cell. They slowly cross the membrane into the cell. What term describes this action? Does it require energy?

Answer 1

Diffusion

No

Step-by-step explanation:

The term that describes the action is diffusion.

By definition, diffusion is the movement of molecules from the region of higher concentration of the molecule to the region of lower concentration of the same molecule.

The process of diffusion requires no energy. That is, it is a spontaneous process.
