List the steps of phagocytosis in the correct order:
1. C3b receptors of the phagocyte recognize and bind to the C3b component of the bacteria.
2. Digestion occurs in the phagolysosome.
3. Exocytosis dispels digested contents from the phagocyte.
4. Digestive enzymes are released.
5. The microorganism is contained in a phagosome.
6. The microorganism undergoes opsonization.
