An invertebrate, such as an insect, has innate immunity that can be nonspecific about which pathogens are prevented from harming its metabolism. Which of the following is most likely to function this way in the insect's intestine?
A)complement
B)lysozyme
C)mucus
D)neutrophils
E)dendritic cells

Question

Quizplus · Accepted Answer

Lysozyme is an enzyme that can degrade bacterial cell walls and is present in the insect intestine as a part of the nonspecific innate immunity. It is not specific to any particular pathogen, making it nonspecific in its mechanism of action. Complement is a system of proteins that act in a sequence to opsonize pathogens and recruit immune cells, while neutrophils and dendritic cells are types of immune cells. Mucus is a physical barrier that can prevent pathogens from entering the body but is not part of the insect's innate immune response.
