Facilitated diffusion (also known as facilitated transport or passive-mediated transport) is the process of spontaneous passive transport (as opposed to active transport) of molecules or ions across a biological membrane via specific transmembrane integral proteins.irst, the transport relies on molecular binding between the cargo and the membrane-embedded channel or carrier protein. Second, the rate of facilitated diffusion is saturable with respect to the concentration difference between the two phases; unlike free diffusion which is linear in the concentration difference.
Queen Elsa of Arendelle is a fictional character who appears in Walt Disney Animation Studios ' 53rd animated film Frozen (2013). She is voiced primarily by Broadway actress and singer Idina Menzel. At the beginning of the film, she is voiced by Eva Bella as a young child and by Spencer Lacey Ganus as a teenager.
