Which type of cellular transport moves molecules from low concentrations to high concentrations?
|
|
Osmosis
|
|
|
Diffusion
|
|
|
Passive Transport
|
|
|
Protein Pumps
|
Explanation:
Detailed explanation-1: -During active transport, substances move against the concentration gradient, from an area of low concentration to an area of high concentration. This process is “active” because it requires the use of energy (usually in the form of ATP). It is the opposite of passive transport .
Detailed explanation-2: -Protein pumps are transmembrane proteins, which are involved in the active transport of ions across the membrane against the concentration gradient.
