Key Concepts

Active Transport

Active transport is a cellular process in which molecules or ions are moved across a cell membrane against their concentration gradient, that is, from an area of lower concentration to an area of higher concentration. This process requires energy input, usually derived from ATP, and involves specific transport proteins.

Passive Transport

Passive transport refers to the movement of molecules or ions across a cell membrane along their concentration gradient, from high concentration to low concentration, without the use of cellular energy. This process includes diffusion and osmosis, where movement occurs due to the natural kinetic energy of the molecules.

Facilitated Diffusion

Facilitated diffusion is a type of passive transport that involves specific transmembrane proteins or channels to help move molecules across the cell membrane down their concentration gradient. Although it aids in the selective transport of substances, it does not require energy input.

Concentration Gradient

A concentration gradient is a difference in the concentration of a substance between two regions. It represents the driving force for diffusion, where molecules naturally move from an area of higher concentration to one of lower concentration, unless energy is expended to move them in the opposite direction.
