This is done with the help of a protein called a transporter. The transporter binds to the molecule and carries it across the membrane.<\/p>\n<h2><span class=\"ez-toc-section\" id=\"Transmembrane_Proteins\"><\/span>Transmembrane Proteins<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<ul>\n<li>Proteins that span the membrane are called transmembrane proteins. They are amphipathic, meaning they have both a hydrophobic and a hydrophilic region. The hydrophobic region interacts with the hydrophobic region of the lipid bilayer, and the hydrophilic region interacts with the water on the outside of the cell. This arrangement creates a hydrophobic core that stabilizes the lipid bilayer.<\/li>\n<li>Transmembrane proteins play important roles in the cell. They transport molecules and ions across the membrane, and they act as receptors or enzymes. Some transmembrane proteins are anchored in the membrane by a hydrophobic region, and others are anchored by a hydrophilic region.<\/li>\n<\/ul>\n<h2><span class=\"ez-toc-section\" id=\"What_assists_the_Movement_of_Substances_by_Facilitated_Diffusion_in_a_System\"><\/span>What assists the Movement of Substances by Facilitated Diffusion in a System?<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p>What assists the Movement of Substances by Facilitated Diffusion in a System?<\/p>\n<p>The movement of substances by facilitated diffusion in a system is assisted by a number of factors, including the presence of proteins called facilitators or channels. These proteins create a pathway through the cell membrane that allows specific molecules to diffuse more easily. The concentration gradient of the molecule being transported is also important, as is the size of the molecule. facilitated diffusion can only occur if the molecule is small enough to fit through the protein channels.<\/p>\n<h2><span class=\"ez-toc-section\" id=\"How_does_Facilitated_Diffusion_work\"><\/span>How does Facilitated Diffusion work?<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p>Facilitated diffusion is the process of molecules passing through a membrane by means of a protein carrier. The protein carrier is specific for the molecule and helps it to cross the membrane. This is a passive process and does not require energy.<\/p>\n<h2><span class=\"ez-toc-section\" id=\"What_is_a_Facilitated_Diffusion_Example_in_Real_Life\"><\/span>What is a Facilitated Diffusion Example in Real Life?<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p>A facilitated diffusion example in real life can be seen when a molecule crosses a cellular membrane. In order for the molecule to cross the membrane, it must first be able to dissolve in the lipid bilayer of the membrane. Once it is dissolved, it can then diffuse through the hydrophobic region of the membrane. Finally, it will cross the hydrophilic region of the membrane and enter the cell.<\/p>\n<h2><span class=\"ez-toc-section\" id=\"Fun_Facts_on_Facilitated_Diffusion\"><\/span>Fun Facts on Facilitated Diffusion<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<ul>\n<li>Facilitated diffusion is the process of passive transport across a cell membrane of a solute molecule down its concentration gradient.<\/li>\n<li>This occurs as a result of the presence of a specific protein called a transporter that is embedded in the cell membrane.<\/li>\n<li>Facilitated diffusion does not require energy and is a relatively slow process.<\/li>\n<\/ul>\n","protected":false},"excerpt":{"rendered":"<p>What is Facilitated Diffusion?
