Select the answer with an INCORRECT statement about the hydrophobic effect It is important for protein folding O It is driven by entropy It is the effect that dictates the way water molecules organize themselves around non-polar substances It allows amphiphilic molecules to form micelles and bilayers O It helps minimizing the contact between polar and non-polar substances

Lipid bilayers form spontaneously in a process driven by the hydrophobic effect. Explain how the hydrophobic effect drives bilayer formation from individual lipids in an aqueous environment. Describe how the physical properties of the lipid bilayer are determined by the chemical properties of the membrane lipid components. Diagrams are encouraged for both parts of the question.
