Diffusion.
Diffusion is the phenomenon that explains the movement of any kind of molecule from areas of higher concentration to lower concentration. This process occurs due to the random motion of molecules and is driven by the concentration gradient to achieve equilibrium.
Diffusion
The concentration gradient is the difference in concentration of a molecule between one area and an adjacent area. This difference creates a gradient that drives the movement of molecules from an area of higher concentration to an area of lower concentration, a process known as diffusion.
The movement of particles from an area of low concentration to high concentration is an active process.

The movement of substances against their concentration gradient is an active process.
Diffusion is the process that allows movement of gases and ions from areas of high concentration to low concentration. This process occurs passively, driven by the concentration gradient, and does not require energy input from the cell.
The movement of particles from areas of high concentration to areas of low concentration is called diffusion. This process occurs spontaneously and helps to equalize the concentration of particles in a system.
active transport
active transport, specifically through a process known as secondary active transport or cotransport. This process relies on the use of energy generated by the concentration gradient of another molecule, usually sodium ions, to drive the movement of glucose against its gradient.
This process is called passive transport or facilitated diffusion, where sugar molecules move down their concentration gradient without requiring energy input from the cell. Proteins in the membrane facilitate the movement of sugar molecules across the membrane.
