Question

Molecules "pumped" in or out from low to high concentration:

Answer 1

Active Transport

Step-by-step explanation:

During active transport, molecules move from an area of low concentration to an area of high concentration. This is the opposite of diffusion, and these molecules are said to flow against their concentration gradient. Active transport is called "active" because this type of transport requires energy to move molecules.

Answer 2

if u are talking about transport in cell then molecules pumps in from high to lower concentration.
