How can the cell move sodium out of the cell

Web13 de jan. de 2016 · The process that could move sodium out of the cell is the active transport. Explanation; -Active transport involves the movement of particles or molecules across a membrane against a concentration gradient (from a region of their lower concentration to a region of their higher concentration). WebThere are many other solutes that must undergo facilitated diffusion to move into a cell, such as amino acids, or to move out of a cell, such as wastes. Figure 3.1.4 – Facilitated Diffusion: (a) Facilitated diffusion of substances crossing the cell (plasma) membrane takes place with the help of proteins such as channel proteins and carrier proteins.
