Question

Transport of molecules occurs against the concentration gradient by using energy in ___ process.

Answer 1

Active transport:

1. Movement of molecules from their lower concentration to their higher concentration through a cell membrane using energy is called active transport.
2. Minerals cannot be absorbed by osmosis and therefore are taken up by active transportation process.
3. Energy is required for the movement of molecules as it is against the gradient.

Final answer: Transport of molecules occurs against the concentration gradient by using energy in active transport process.
