- Bacterial Toxins
- Bacterial Exotoxins
- Type III Cytotoxins
Included Quiz Questions
Which of the following is FALSE regarding exotoxins?
- They contain a secretory injection system.
- They are secreted by bacteria.
- Most of them have an AB structure.
- They often bind receptors on human cells.
- They break up in the cell cytoplasm, where they mediate cell damage.
What is the purpose of the secretory injection system in type III cytotoxins?
- To inject toxins directly into human cells
- To inactivate host cell receptors, allowing toxins to enter the cell directly
- To bind directly to host cell receptors to enter the cytoplasm
- To directly kill the host cell
How does the diphtheria toxin impede protein production in target cells?
- ADP ribosylation of eEF-2
- Increase of cAMP via adenylate cyclase activity
- Increase of ADP, which increases cAMP
- ADP ribosylation of adenylate cyclase
- Inactivation of eEF-2 via an increase in cAMP
