Passive transport

Facilitated diffusion is a passive process the solutes move down their concentration gradient and do not require the expenditure of cellular energy for this process Carrier proteins and channel proteins allow for the diffusion of molecules across the cell membrane Carrier proteins undergo conformational alterations to allow

Diffusion and passive transport (article) | Khan Academy

The simplest forms of transport across a membrane are passive Passive transport does not require the cell to expend any energy and involves a substance diffusing down its concentration gradient across a membrane A concentration gradient is a just a region of space over which the concentration of a substance changes,

Does Diffusion Require A Membrane? Why Or Why Not? | Cheggcom

Answer to Does diffusion require a membrane? Why or why not?

Cell Membranes Problem Set

A Simple diffusion does not require energy facilitated diffusion requires a source of ATP B Simple diffusion can only move material in the direction of a concentration gradient; facilitated diffusion moves materials with and against a concentration gradient C Simple diffusion is not saturable; facilitated diffusion rates are

Facilitated Diffusion - Pearson - The Biology Place

The solute can move "downhill," from regions of higher to lower concentration, relying on the specificity of the protein carrier to pass through the membrane This process is called passive transport or facilitated diffusion, and does not require energy The solute can move "uphill," from regions of lower to higher concentration

The Cell Membrane: Diffusion, Osmosis, and Active Transport

Diffusion is one form of passive transport that doesn't require the expenditure of cellular energy A molecule can diffuse passively through the cell membrane if it's lipid soluble, uncharged, and very small, or if a carrier molecule can assist it The unassisted diffusion of very small or lipid soluble particles is called simple

homework - Diffusion across cell membranes - Biology Stack Exchange

With respect to cell membranes, anything that can diffuse freely will be the same concentration inside and outside the cell It doesn't require metabolic energy as the cell doesn't need to do a thing Thus the answer is A Facilitated diffusion is where the cell puts protein channels on its membrane to allow
