C)approximately neutral.
D)moderately basic.
E)very basic.

Question

Quizplus · Accepted Answer

The pH of the solution should be approximately neutral (around pH 7) for bilayers to form spontaneously. This is because the two layers of the bilayer are made up of phospholipid molecules, which have both hydrophilic (water-loving) and hydrophobic (water-fearing) regions. At neutral pH, the hydrophilic regions of the phospholipids interact with the surrounding water molecules, while the hydrophobic regions interact with each other to form the bilayer structure. If the pH is too acidic or basic, the charges on the phospholipids and/or the water molecules could be altered, disrupting the interactions necessary for bilayer formation.
