Final answer:
Enzymes are substances that operate immune mechanisms by playing a role in the innate immune response. They facilitate the destruction of pathogens and enhance phagocytosis.
Step-by-step explanation:
The substances that operate immune mechanisms are called immune effectors. Immune effectors can be categorized into two main types: immune cells and immune molecules. Immune cells, such as white blood cells, detect and eliminate pathogens through various mechanisms like phagocytosis and producing chemicals that promote inflammation. Immune molecules, such as antibodies and complement proteins, interact with pathogens and facilitate their destruction.
Enzymes are one type of immune molecule that plays an important role in the innate immune response. They can help break down pathogens and enhance the efficiency of phagocytosis. Enzymes like lysozyme and proteases are examples of immune enzymes that are found in various immune cells.
Therefore, the correct answer is option c. enzymes. Enzymes are an important component of the immune system and contribute to its functioning alongside other immune mechanisms.
