What is the main difference between components of the adaptive immune system and the innate immune system?
What is the main difference between components of the adaptive immune system and the innate immune system?
- Adaptive immunity components recognize specific antigenic determinants, while innate immunity components recognize shared features of foreign molecules. (correct)
- Innate immunity components participate in a limited number of effector functions, unlike the adaptive immunity components.
- Innate immunity components bind to T-cell receptors, while adaptive immunity components bind to MHC molecules.
- Adaptive immunity components are found in the blood, while innate immunity components are membrane-bound.
