Question

The movement of molecules or ions from a region of their lower concentration to

a region of their higher concentration,i.e. against the concentration gradient is

called __________​

Answer 1

Answer:

active transport

In cellular biology, active transport is the movement of molecules across a cell membrane from a region of lower concentration to a region of higher concentration—against the concentration gradient. Active transport requires cellular energy to achieve this movement

Answer 2
