Small nonpolar hydrophobic molecules
WebView full document. 37. Hydrophobic interactions between nonpolar molecules ______. A) result from the tendency of water to maximize contact with nonpolar molecules B) are the result of strong attractions between nonpolar molecules C) are the result of strong repulsion between water and nonpolar molecules D) depend on strong permanent dipoles ... WebSep 12, 2024 · Small, nonpolar molecules are hydrophobic, so they can easily cross the phospholipid bilayer of the plasma membrane. Polar molecules and ions are hydrophilic, so they cannot very easily cross the hydrophobic portion of the plasma membrane (formed by the phospholipid tails). How do water soluble molecules cross the membrane?

Based on the information presented, how does aldosterone most likely enter target cells See answer Advertisement pau785 Answer: …
Web1) Correct option is (a) Cell membranes are made predominantly of lipids as a result of which they are hydrophobic in nature. Small nonpolar (hydrophobic) molecules can easily move through cell membranes vi … View the full answer Transcribed image text: WebIn contrast, nonpolar hydrophobic tail does not readily interact with water, but instead interacts with other nonpolar tail groups or hydrophobic molecules. For example, a micelle forms when polar head groups of a lipid interact with water and the hydrophobic tails of the lipids interact with each other, excluding water.
WebDec 5, 2024 · Small nonpolar molecules, such as O2 and CO2, are soluble in the lipid bilayer and therefore can readily cross cell membranes. Small uncharged polar molecules, such as H2O, also can diffuse through membranes, but larger uncharged polar molecules, such as glucose, cannot.
