Movement of ions or molecules in a direction opposite to that of prevailing electrochemical gradient is known as
-
- diffusion
- active transport
- pinocytosis
- brownian movement
Correct Option: B
Movement of ions against concentration gradient involves the expenditure of energy. Diffusion involves the movement of solute particles from region of higher concentration to a region of lower concentration. Pinocytosis is cell drinking. Brownian movement is the random to and fro movement of atoms and molecules.
