Question

which term describes when a molecule moves from low to high concentration?
respiration
osmosis
active transport

Explanation:

• Respiration is the process of converting nutrients into energy.
• Osmosis is the movement of water molecules from a region of low solute concentration to a region of high solute concentration across a semi - permeable membrane.
• Active transport is the movement of molecules against the concentration gradient (from low to high concentration) with the use of energy (usually ATP).

Answer:

Active transport
