Which mucous membrane-related defense degrades the cell walls of pathogenic bacteria? Chitinase Cytokine Lysozyme Mucin Macrophage What part of the innate immune system has the ability to recognize and destroy our cells that infected or cancerous? Complement System Helper T-Cell Membrane Attack Complex Natural Killer Cell Pattern Recognition Receptor What allows phagocytes to detect specific groups of pathogens and parasites? Chitinase recognition receptors Mucin recognition receptors Lysozyme receptors Pattern recognition receptors Complement system proteins A mast cell recognized a foreign invader. How will this mast cell respond? Membrane attack complex formation Chitinase enzyme secretion Histamine secretion Pattern recognition receptor secretion Mucin secretion The anti-microbial properties of the skin do not include - Frequent replacement Lack of moisture Poor nutritional content High iron content Acid layer (acid mantle)Explanation / Answer
Answer:
Correct Answer
31) Lysozyme
Explanation: It is an antimicrobial enzyme found in secretions like saliva, tears, mucus. It catalyzes the hydrolysis of parts of pepetidoglycan that makes the bacterial cell wall causing lysis of the bacteria.
32) Natural Killer Cell
Explanation: Natural killer cells are a part of the innate immune system and have the ability to distinguish between healthy and malignant (cancerous) cells.
33) Pattern recognition receptors
Explanation: Pattern recognition receptors are molecules found on phagocytes like macrophages and detect pathogen associated molecular patterns.
34) Histamine secretion
Explanation: Histamine secretion leads to swelling, redness in the case of a foreign infection.
35) High iron content
Explanation: It is not an antimicrobial property of the skin.
