Which type of cellular transport moves molecules from low concentrations to high concentrations?
|
|
Osmosis
|
|
|
Diffusion
|
|
|
Passive Transport
|
|
|
Protein Pumps

Explanation:
Detailed explanation-1: -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.
Detailed explanation-2: -During active transport, a protein pump uses energy, in the form of ATP, to move molecules from an area of low concentration to an area of high concentration.
Detailed explanation-3: -ACTIVE TRANSPORT It is also possible to move substances across membranes against their concentration gradient (from areas of low concentration to areas of high concentration).
