WebMolecules that practice simple diffusion must be small and nonpolar*, in order to pass through the membrane. Simple diffusion can be disrupted if the diffusion distance is increased. If the alveoli in our lungs fill with fluid (pulmonary edema), the distance the gases must … WebMay 26, 2024 · Small, nonpolar hydrophobic molecules such as fatty acids a. pass readily through a membrane's lipid bilayer b. diffuse very slowly through the lipid bilayer c require special channels to enter a cell d. are actively transported across cell membranes c. must enter the cell via endocytosis See answers Advertisement samueladesida43 Answer:
WebMay 1, 2024 · The hydrophobic portion of the lipids is the non-polar long hydrocarbon chains of two fatty acids. The fatty acids are present as esters bonded to glycerol. The third-OH … WebBy aggregating together, nonpolar molecules reduce the surface area exposed to water and minimize their disruptive effect. The hydrophobic effect can be quantified by measuring the partition coefficients of non-polar molecules between water and non-polar solvents.
Web1, because testosterone is nonpolar and can diffuse through the membrane. 2, because testosterone covalently binds to a surface protein and transports into the cell. 3, because testosterone dissolves in water and flows through the channel. 4, because testosterone is filtered out of the extracellular fluid and taken into the cell by endocytosis.
