WebLigands that can enter the cell Small, hydrophobic ligands can pass through the plasma membrane and bind to intracellular receptors in the nucleus or cytoplasm. In the human body, some of the most important ligands of this type are the steroid hormones. WebMar 5, 2024 · Small nonpolar molecules can easily diffuse across the cell membrane. However, due to the hydrophobic nature of the lipids that make up cell membranes, polar molecules (such as water) and ions cannot do so. Instead, they diffuse across the membrane through transport proteins.

Can polar substances pass through the cell membrane?

WebHow does being hydrophobic or hydrophilic affect how molecules enter a cell? Uncharged molecules are able to cross membranes at higher rates than charged molecules. Small molecules are able to cross membranes … WebAnswer: Different membrane proteins are associated with the membranes in different ways. Many extend through the lipid bilayer, with part of their mass on either side. Like their lipid neighbors, these transmembrane proteins are amphipathic, having regions that are hydrophobic and regions that ar... WebHydrophilic, or water-soluble, hormones are unable to diffuse through the lipid bilayer of the cell membrane and must therefore pass on their message to a receptor located at the surface of the cell. iphone stockage plein
