Which of the following is NOT true of phospholipid bilayers? Membrane budding requires transient breakages in the bilayer membrane. The interior of phospholipid bilayers is a highly hydrophobic environment. Phospholipid bilayers separate the cell from the exterior environment as well as from compartments within the cell. The chemical properties of phospholipids lead to the spontaneous formation of bilayers.

Membrane budding requires transient breakages in the bilayer membrane.

Explanation:

Membrane budding is the process of formation of outgrowth or ingrowth from the surface of the membrane followed by its detachment. It serves many functions such as vesicular transport, the release of enveloped viruses, etc.

The process of membrane budding is regulated by proteins and does not introduce any breaks in the membrane.

For example, during vesicular transport, small vesicle grows on the surface membrane of the parent organelle. These vesicles are coated with specific proteins. Once these vesicles bud off from the parent organelle, they shed off the coat and fuse with the target organelle.
