Question

A critical feature of the plasma membrane is that it is selectively permeable. This allows the plasma membrane to regulate transport across cellular boundaries-a function essential to any cell's existence. How does phospholipid structure prevent certain molecules from crossing the plasma membrane freely? Drag the labels to fill in the table. Use only white labels for white targets, pink labels for pink targets, and blue labels for blue targets Reset Help transport protein required to cross efficiently have difficulty crossing the hydrophobic part no transport protein required hydrophilic hydrophobic can cross easily Type of molecule Hydrophobic or hydrophilic? Able to cross lipid bilayer? Transport protein required? Nonpolar molecules (examples: hydrocarbons, O2. CO2) Polar molecules (examples: water, sugars) Ions (examples: Nat, K+, Ca2+, cr)
