Question

which type of transport is used to move s molecule from a region of low concentration to a region of high concentration

Answer 1

Facilated diffusion only works from high to low concentration. A transport protein binds to the substance on one side of the cell membrane and then releases it on the other side. ACTIVE TRANSPORT involves the transport of molecules from regions of low concentration to regions of high concentration.

Answer 2

Active transport.

Step-by-step explanation:

Active transport is the process in which molecules or particle move against the gradient i.e from regions of lower concentration to the regions of higher concentration. In bio process, molecules undergoing active transportation usually move by utilizing the energy produced during respiration. The active transportation usually takes place when some molecules are at high concentration inside the cell but they are required by the organism, then carrier protein moves these specific molecules through the process of active transport.
