Q: Which of the following is NOT a component of the innate immune system?
Solution: Antibodies are part of the adaptive immune system, while macrophages, natural killer cells, and complement proteins are components of the innate immune system.
Steps: 4
Step 1: Understand what the innate immune system is. It is the body's first line of defense against infections and includes various cells and proteins that respond quickly to pathogens.
Step 2: Identify the components of the innate immune system. These include macrophages, natural killer cells, and complement proteins.
Step 3: Recognize that antibodies are not part of the innate immune system. Instead, they are part of the adaptive immune system, which develops a targeted response to specific pathogens.
Step 4: Conclude that the correct answer to the question is antibodies, as they do not belong to the innate immune system.
