ANSWERS
What makes a good antigen good?
- Bigger is better
- Some molecules are more antigenic than others
Order carbohydrates, proteins, & lipids
Proteins > carbs > lipids
What are antibodies?
- Glycoproteins of 150k-180k
- 4 polypeptide chains
- Held together by disulfide bonds
How do antibodies & antigens work together?
"Lock & key" strategy
How do antibodies help decrease the impact of pathogens?
- Bound antibodies provide a handle for phagocytes
- Bound antibodies prevent pathogens from attaching to host cells
- Antibodies bind to toxins to neutralize them
