WebMay 23, 2024 · Examples of Facilitated diffusion 1. Glucose and amino acid Transport The transport of glucose and amino acid from the bloodstream into the cell is an example of facilitated diffusion. In the small intestine, these molecules are taken in via active transport and then are released into the bloodstream. WebDiffusion is the process by which molecules or particles spread from areas of high concentration to areas of low concentration. This movement occurs due to the random motion of particles and is a fundamental concept in physics, chemistry, and biology.
