Which of the following would spontaneously form a liposome if suspended in aqueous solution at pH 7 and sonicated? fatty acids triacylglycerides. glycerophospholipids. sphingomyelins. cholesterol.

Serves as biological catalysts for chemical reactions. Form membrane bilayers when a group of these molecules are together, Provides a wav for cells to communicate with each other.Contracts and moves cellular componentsStores genetic and hereditary information.

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.

Cholesterol maintains the fluidity and stability of membranes at different temperatures. Cholesterol, therefore, ensures that the lipid bilayer Is always packed firmly Always has sugar molecules Is always moving Is destroyed
