1.When the first protein in the complement series (C1q) is activated by an antibody that has been made in response to a microbe (e.g., bacteria), this initiates the chain of events resulting in the generation of MAC that causes lysis of the microbe. This is known as the Selected Answer: Inflammatory pathway Answers: alternative activation pathway lectin activation pathway Inflammatory pathway classical activation pathway 2.The include basophils, eosinophils, and neutrophils. Selected Answer: monocytes Answers: agranulocytes granulocytes monocytes reticuloendothelial system (RES)

Answer :

1. This is known as the classical activation pathway. Option 4. 2. The granulocytes include basophils, eosinophils, and neutrophils. Option 3.

1. When the complement protein, C1q, is activated by an antibody that the body has produced in response to a microbe such as bacteria, this initiates a sequence of events resulting in the generation of Membrane Attack Complexes (MAC) that lyses or breaks down, the microbe.

This process is known as the classical activation pathway, not the inflammatory pathway. Therefore, the correct answer is Option 4.

2. Meanwhile, basophils, eosinophils, and neutrophils are types of granulocytes, not monocytes. These different types of cells play crucial roles in the body's immune response to infections.

Therefore, the correct answer is Option 3. granulocytes.
