Question

List the steps of phagocytosis in the correct order.

1. C3b receptors of the phagocyte recognises and binds to C3b bound to the bacteria

2. Digestion occurs in the phagolysosome

3. Exocytosis of digested contents from the phagocyte

4. Release of digestive enzymes

5. The microorganism is contained in a phagosome

6. The microorganism undergoes opsonization

2, 4, 1, 3, 6, 5
