Cool Scientists Study Cells

Catalysis

chemical reactions sped up by molecules (enzymes/ribozymes).

Self-replication

molecules making copies of themselves (like RNA).

Self-assembly

molecules organizing spontaneously into structures (e.g., membranes, ribosomes).

Compartmentalization

formation of internal environments (membranes, vesicles).

What is the role of vesicles in the spontaneous origin of cells?

Vesicles form spontaneously from fatty acids, creating membrane-bound compartments that allow different internal conditions.”
