문제 3
선택형
What is the primary role of C3 in the Complement System?
- To act as a distress beacon
- To switch from passive to active
- To neutralize water molecules
- To produce antibodies
문제 4
선택형
What happens when C3b protein finds a target?
- It anchors tightly to the surface of the target
- It gets neutralized by water molecules
- It deactivates other proteins
- It produces antibodies
문제 5
선택형
What does the C3 Convertase platform do?
- Activates more C3 proteins
- Produces antibodies
- Neutralizes water molecules
- Destroys viruses directly
문제 6
선택형
How do passive immune cells react to C3a proteins?
- They become neutralized
- They become active and follow the protein tracks
- They produce antibodies
- They deactivate other proteins
문제 7
선택형
What is the role of phagocytes in the Complement System?
- To produce antibodies
- To swallow and kill enemies with acid
- To neutralize water molecules
- To deactivate complement proteins
문제 8
선택형
What structure is formed by complement proteins on the surface of bacteria to kill them?
- Antibody complex
- Membrane Attack Complex
- Neutralizing complex
- Defensive barrier
문제 9
선택형
Why are viruses particularly vulnerable to the Complement System?
- They can’t produce antibodies
- They need to travel from cell to cell and are defenseless outside of cells
- They are neutralized by water molecules
- They deactivate upon contact with C3 proteins
문제 10
선택형
How do some bacteria evade the Complement System?
- By producing antibodies
- By becoming invisible through certain molecules
- By neutralizing water molecules
- By deactivating C3 proteins
문제 11
선택형
What is the main purpose of the C3a protein?
- To bind tightly to bacteria
- To act as a distress beacon
- To neutralize water molecules
- To produce antibodies
문제 12
선택형
What happens when complement proteins change their shape?
- They deactivate
- They can interact with other proteins and activate them
- They produce antibodies
- They neutralize water molecules
문제 13
선택형
What analogy is used to describe the activation of complement proteins?
- A ticking clock
- Falling dominoes
- A chain reaction
- Matches igniting a fire
문제 14
선택형
How do complement proteins assist phagocytes?
- By producing antibodies
- By neutralizing water molecules
- By acting as a glue to help catch bacteria
- By deactivating other proteins
문제 15
선택형
What is the final outcome of the Membrane Attack Complex on bacteria?
- It produces antibodies
- It neutralizes water molecules
- It rips holes in bacterial membranes, causing them to die
- It deactivates bacteria
문제 16
선택형
Why is the Complement System particularly effective against viruses?
- Viruses can’t produce antibodies
- Viruses need to travel between cells and are defenseless outside of them
- Viruses deactivate upon contact with C3 proteins
- Viruses neutralize water molecules
문제 17
선택형
What is the role of C3 Convertase in the complement cascade?
- To deactivate other proteins
- To produce antibodies
- To activate more C3 proteins
- To neutralize water molecules
문제 18
선택형
How do some viruses avoid the Complement System?
- By producing antibodies
- By shutting down complement activation through specific proteins
- By neutralizing water molecules
- By deactivating C3 proteins
문제 19
선택형
Why do we still get sick despite having the Complement System?
- The Complement System is not always active
- The Complement System is not effective against all pathogens
- Pathogens adapt and find ways to evade the Complement System
- The Complement System produces antibodies
문제 20
선택형

- A type of virus
- A cell that swallows and kills pathogens with acid
- A complement protein
- A distress beacon
