Diffusion against active transport

2021-06-06 11:02 AM

Although there are many variations of the underlying mechanisms, diffusion means random movement of the molecule, either across intermolecular spaces or in association with carrier proteins.

There are two ways of transporting substances across membranes, both directly across the membrane as well as through transmembrane proteins: diffusion and active transport, also known as active transport.

Although there are many variations of the underlying mechanisms, diffusion means random movement of the molecule, either across intermolecular spaces or in association with carrier proteins. The energy of this process is the kinetic energy of the substances.

In contrast, active transport means the movement of a substance or ions across a membrane by binding to a carrier protein by which the carrier protein induces movement of substances against a concentration scale, such as from areas of low concentration to where concentrations are high. This movement requires another source of energy besides the kinetic energy of the molecule.
