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. 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. WebA water molecule has polar O-H bonds that result in regions of partial positive charge (hydrogen atoms) and a region of partial negative charge (oxygen atom with lone pairs).
