Based on Figure 25.4 a , which of the following statements about vesicle self-assembly is most accurate?

  • A: Vesicle self-assembly occurs at a constant rate over time, regardless of the presence of montmorillonite clay.
  • B: The presence of montmorillonite clay significantly increases the rate and total yield of vesicle self-assembly.
  • C: Montmorillonite clay inhibits vesicle self-assembly, leading to fewer vesicles being formed.
  • D: Vesicle self-assembly only occurs in the presence of montmorillonite clay.

Explanation

Figure 25.4 a clearly illustrates that the 'Precursor molecules plus montmorillonite clay' curve blue line shows a much faster rate of increase in relative turbidity an index of vesicle number and reaches a higher plateau compared to the 'Precursor molecules only' curve red line . This indicates that montmorillonite clay significantly accelerates and increases the overall efficiency of vesicle self-assembly.
