NEET BIOLOGY

Detailed explanation-1: -In the process of diffusion, a substance tends to move from an area of high concentration to an area of low concentration until its concentration becomes equal throughout a space.

Detailed explanation-2: -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).

Detailed explanation-3: -Active transport is the movement of dissolved molecules into or out of a cell through the cell membrane, from a region of lower concentration to a region of higher concentration. The particles move against the concentration gradient, using energy released during respiration .

Detailed explanation-4: -The movement of ions or molecules against a concentration gradient with the utilisation of energy is known as active transport.

Detailed explanation-5: -Diffusion: Diffusion is the movement of particles from an area of higher concentration to lower concentration.
